archiso/mkarchiso: clear environment variables when chrooting

Browse Source 
Environment variables can interfere with the commands in chroot.
This causes issues when the environment variables specify a path that does not exist inside the chroot, e.g. if TMPDIR is set to a custom value.

Fixes https://bugs.archlinux.org/task/70580 .
