[PATCH] t0001: don't let a default ACL interfere with the umask test

The "init creates a new deep directory (umask vs. shared)" test expects
the permissions of newly created files to be based on the umask, which
fails if a default ACL is inherited from the working tree for git.  So
attempt to remove a default ACL if there is one.  Same idea as
8ed0a740dd42bd0724aebed6e3b07c4ea2a2d5e8.  (I guess I'm the only one who
ever runs the test suite with a default ACL set.)
