Refuse dbus message paths longer than BUS_PATH_SIZE_MAX limit.

Even though the dbus specification does not enforce any length limit on the
path of a dbus message, having to analyze too long strings in PID1 may be
time-consuming and it may have security impacts.

In any case, the limit is set so high that real-life applications should not
have a problem with it.
