optee: upgraded recipes to 3.10

The optee recipes were upgraded due to issues booting with 3.8
on qemuarm64-secureboot, which were resolved by the upgrade.
The 3.8 recipes are retained for backwards compatibility.

optee-test and optee-examples were modified to pass a sysroot
to the LIBGCC_LOCATE_CFLAGS parameter, to ensure proper location
of the libgcc library.

Recipes have been renamed to reflect their current version.
As this makes the PV variables redundent, these have been removed.

Patch 0006 has been refreshed to work with 3.10 without fuzzing.
The original copy has been retained for the 3.8 recipes to use.
