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.
