tee_shm_allocate(): use size_t for size and check for overflow

Fixes failure of xtest 7002 on Foundation_v8 (PLATFORM=vexpress-fvp).

xtest 7002 calls TEEC_AllocateSharedMemory() with a requested size of
0xFFFFFFFE and expects an out-of-memory error. Prior to this commit,
the size after page_size alignment would wrap to 0 and no error would be
returned.

Tested on PLATFORM vexpress-fvp and vexpress-qemu_virt.
