sd-bus: query pid also when searching for supplementary gids

Browse Source 
If the SD_BUS_CREDS_SUPPLEMENTARY_GIDS value is requested, the pid is
queried to find out the supplementary gids value from /proc/pid/status.
Otherwise sd_bus_creds_get_supplementary_gids() won't work unless some
other value in mask triggered fetching the pid information.
