[PATCH 2/2] Don't rely on strerror text when testing rmdir failure

[Charles Bailey <cbailey32@bloomberg.net>]

AIX doesn't make a distiction between EEXIST and ENOTEMPTY so relying on
the strerror string for the rmdir failure is fragile. Just test that the
start of the string matches the Git controlled "failed to rmdir..."
error. The exact text of the OS generated error string isn't important
to the test.
