Subject: [PATCH] update_chroot: set a more permissive ccache umask

This seems to fix the ccache permission issues `update_chroot` hits
while building ninja.

The erroneous files were created as root:portage, so a umask of 002
should let other portage group members share them, which seems entirely
reasonable.
