util: add Mac-specific check whether we're in a GUI session (issue2553)

The previous test assumed that 'os.name' was "mac" on Mac OS X. This
is not the case; 'mac' was classic Mac OS, whereas Mac OS X has 'os.name'
be 'posix'.

Please note that this change will break Mercurial on hypothetical
non-Mac OS X deployments of Darwin.

Credit to Brodie Rao for thinking of CGSessionCopyCurrentDictionary()
and Kevin Bullock for testing.
