archbuild: use better umask

In commit 40a90e2cab479cc64903a62b42eb617a8a7e5842 we tried to protect
against system umasks resulting in unreadable chroots. However, we tried
to do this in a targeted manner due to not wanting to fiddle with
permissions for user-owned files. Unfortuantely, mkdir -p -m755 does not
actually work that way -- the parent directory is created with broken
permissions. We need umask.

Run umask and mkdir in a subshell to prevent leakage.
