CTS test for libmedia OOB write anywhere

Set up a DRM session, spoof the non-secure device as
secure and pass an invalid pointer as the decrypt
destination buffer address which causes a segfault in
mediaserver on devices without the patch.

This test only runs on non-secure (L3) devices, it is
skipped on secure devices since the vulnerability doesn't
exist there.
