login: Remove utmp backend jump tables [BZ #23518]
There is just one file-based implementation, so this dispatch
mechanism is unnecessary. Instead of the vtable pointer
__libc_utmp_jump_table, use a non-negative file_fd as the indicator
that the backend is initialized.
(cherry picked from commit 1a7fe2ebe52b3c8bf465d1756e69452d05c1c103)
