[PATCH] t/lib-git.sh: fix ACL-related permissions failure

[Adam Dinwoodie <adam@dinwoodie.org>]

SSH keys are expected to be created with very restrictive permissions,
and SSH commands will fail if the permissions are not appropriate.  When
creating a directory for SSH keys in test scripts, attempt to clear any
ACLs that might otherwise cause the private key to inherit less
restrictive permissions than it requires.

This change is required in particular to avoid tests relating to SSH
signing failing in Cygwin.
