Fixes a mistake in the optee_os install step which prevents the
libraries from being copied into the root FS staging area.

When OP-TEE is built with CFG_ULIBS_SHARED=y, TA shared libraries are
created. They have to be installed into the target root FS in order
to be found at runtime.

This patch adds a custom package to do just that.

Update script based on the feedback from Buildroot maintainer [1]:

 > +# /etc/init.d/optee

 Drop this comment, it is useless, and in fact wrong: the file will not
 have this name in a Buildroot filesystem.

 (...)
 > +	if [ -e /usr/sbin/tee-supplicant -a -e /dev/teepriv0 ]; then

 Drop this test, just start tee-supplicatn.

 (...)
 > +		echo "Starting tee-supplicant..."
 > +		/usr/sbin/tee-supplicant &

 Please use start-stop-daemon. See
 https://patchwork.ozlabs.org/patch/994013/ for the "right" way of
 writing an init script.

This maybe not be best way, if there's one, but it seems more
standard to use start-stop-daemon. Moreover the proposed script
ensures its return value matches the status of the caller request.

For some reason Raspberry Pi 3 with NFS root doesn't allow
tee-supplicant to create a working folder for user 'tee' under the /data
folder. We have found a workaround which is to create the /data
hierarchy and set its permissions in S30optee rather than in the root fs
definition in optee_client.mk.

Using the current tip of the buildroot upstream branch, we get the
following error:

 build$ make
 [...]
 [...]br-ext/package/optee_benchmark/optee_benchmark.mk:8: *** optee_benchmark has local site method, but `OPTEE_BENCHMARK_SITE` is not defined.  Stop.

The error does not occur if BR2_PACKAGE_OPTEE_BENCHMARK is selected (i.e.,
"make CFG_TEE_BENCHMARK=y").

It looks like the _SITE variable has to be declared even though the
package is not selected for building.

If /dev/ion exists, it should be set up so that the test user can access
it. Otherwise, some tests will fail, such as xtest 1014 (Secure Data
Path). Similar to what is done for /dev/tee*, this commit configures
permissions based on a specific group: ion.

Restrict execution of TEE client applications to members of the teeclnt
group. A test user is created and added to this group.
Having two groups (tee and teeclnt) allows to better isolate
tee-supplicant from the client applications.

Init scripts normally print OK or FAIL when they start daemons. Update
our tee-supplicant script to do just that. The -d option to tee-supplicant
is used so that when the tee-supplicant command returns, we  know for sure
if initialization went well or not.

Currently sign.py uses system python to sign TAs. Problem is
that buildroot can build own host-python. This python lacks
pycrypto, so sign.py fails.

This patch adds dependency on host-python-pycrypto, so buildroot
will always build python with needed module.
