fio_plugin: fix hang in FIO

Browse Source 
This is fix for https://github.com/spdk/spdk/issues/523

Fio hangs on pthread_exit(NULL) from spdk thread.
This happens because, pthread_exit tries to dlopen glibc and hangs on
__lll_lock_wait. This patch prevents unmapping of glibc in fio_plugin
and phtread_exit does not need to dlopen it again.
