py3: use pycompat.sysargv in scmposix.systemrcpath() sys.argv returns unicodes on Python 3. We have pycompat.sysargv which returns bytes encoded using os.fsencode(). After this patch scmposix.systemrcpath() returns bytes in Python 3 world. This change is also a part of making `hg version` run in Python 3.
