package/optee-client: remove dependency on BR2_STATIC_LIBS

Restore support for BR2_STATIC_LIBS in optee-client, removed by
[1] to overcome an issue introduced in OP-TEE 3.13.0 that mandates
support for shared libraries.

As OP-TEE expects to be functional on OSes without dynamic shared
library support, change [2] was merged in OP-TEE tag 3.15.0 to fix the
initial issue introducing new configuration switch CFG_TEE_SUPP_PLUGIN.
When disabled, optee-client plugin support is not embedded and
optee-client can built with static libraries support only.
