Subject: Add a testcase for ACL with restrictive umask.

Right now, Git creates unreadable pack files on non-shared
repositories when the user has a umask of 077, even when the default
ACLs for the directory would give read/write access to a specific
user.

Loose object files are created world-readable, which doesn't break ACLs,
but isn't necessarily desirable.
