Relax permissions on osimage
Relax permissions on osimage

Public content has to be world
readable for the web server
to provide it. Mitigate by only
temporarily relaxing umask.

Note that the known sensitive
portions are already doing an
explicit specification of permissions, so umask
relaxing won't affect those.
