tests: Added a script to test the glfs_fini hang fix

The script has been added as '.sh' instead of '.t' to avoid regression 
tests failure which may happen due to instability of glfs_fini.

In addition, there is still some support needed to compile libgfapi* 
tests in our current regression test framework.
