package/optee-client: add option to configure TEE-based storage location

Browse Source 
OP-TEE provides the possibility of secure storage done by the
normal world OS via tee-supplicant.

The location is a compile-time value and by default it is /data/tee .
As this might not be suitable for all use-cases add an option to
set the CFG_TEE_FS_PARENT_PATH compile option.

Default value is still /data/tee as it was before adding this option.
