Create per-uid GCOV_PREFIX dir in the getenv wrapper
Bug: http://b/116873221
With https://reviews.llvm.org/D65245, the profile runtime assumes that
the directory ${GCOV_PREFIX} is already created. Before returning from
the getenv wrapper, create the per-uid ${GCOV_PREFIX}.
Test: cuttlefish builds and boots with new Clang.
