package/optee-*: support BR2_STATIC_LIBS=y

Patch current optee-client 3.4.0 to support building resources
with static linkage of executable binaries with the user libraries.
The optee-client patch is under review in the OP-TEE project [1] and
should be merged in the next OP-TEE release 3.5.0.

This change drops !BR2_STATIC_LIBS constraint on package optee-client
and its dependent packages that are optee-benchmark, optee-examples,
and optee-test.
