libteeacl: Move uuid-dev checking in libteec makefile

For uuid dependency checking, cross compiler version pkg-config should
be used. However top level makefile does not hold the information of the
cross compiler. To solve that, move the checking from top level makefile
to the library level.

Fixes: d448e8bb ("Allow cross-compile pkg-config")
