tests: Fix the spurious failure in libgfapi-fini-hang.t

RCA:
After running libgfapi-fini-hang, there is a EXPECT_WITHIN which waits
for PROCESS_UP_TIMEOUT(20s), for the process libgfapi-fini-hang to die.
Currently EXPECT_WITHIN is returning success even if the process
libgfapi-fini-hang is alive. This is because "pgrep libgfapi-fini-hang"
in check_process() is returning 1(no process alive) even if the process
is alive. Man page of pgrep says "The process name used for matching is
limited to the 15 characters". Hence changing the name of executable from
libgfapi-fini-hang to gfapi-hang, so that it falls within the limit.

As explained the failure is not because there was a hang(logs show that
glfs_set_volfile_server was still executing), but because EXPECT_WITHIN
was not really waiting. And hence there was a race between the execution
of the process libgfapi-fini-hang and the kill.
