add leading prototype for pd_uuid_rng_get_bytes

gcc was giving a warning for a missing prototype.  A prototype isn't
actually needed since there's one in pduuid.h and the function is
only used after it is defined in rng.c, but providing one will suppress
a warning without having to change the compile flags.
