Close file descirptor before fork
FreeBSD chroot(2) fails with EPERM when a directory file descriptor is open
with either `kern.chroot_allow_open_directories` being 0, or when the process
already is inside a chroot. This is exposed in alpm_run_chroot that uses
opendir() to open a file descriptor to the current directory before doing
the forking and chrooting. Since the file descriptor is not used in the
forked process, we close it.
Fixes FS#36161.
