gdbus: fix out-of-bound array access

In path_rule_matches(), the given paths may be of 0-length. Do not
access memory before the array in those case. This is for example
triggered by:

test_match_rule (con, G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_PATH, "/", "", FALSE);

in test_connection_signal_match_rules().

This bug was found thanks to GCC AddressSanitizer.
