alpm_run_chroot: always connect parent2child pipe

Commit e374e6829cea3512f0b4a4069c5a6168f0f8d8a0 closed stdin before
running scripts/hooks.  This left the exec'd process with no file
descriptor 0.  If the process subsequently opened a file it would be
assigned fd 0, and could potentially be confused for stdin.  Connecting
and immediately closing the parent2child pipe ensures that the child has
an fd 0 and that it is empty.
