Avoid mutex lock wait in socket close failure

In case of absence to close a socket fd during an exit from
application we try to close the same by traversing the
socket_fds in swrap_destructor. But the early lock taken on
libc_symbol_binding_mutex inside the destructor blocks the
subsequent request for locking the same while loading
libc_close within swrap_close.

Also added a test case to verify this flaw in destructor.
