Fix double close of the lock file
According to FOPEN(3), using fclose on an fdopen'd file stream also
closes the underlying file descriptor. This happened in _alpm_lckmk
(util.c), which meant that when alpm_trans_release closed it again, the
log file (which reused the original file descriptor) was closed instead.
