sysctl.d: bump number of queueable AF_UNIX/SOCK_DGRAM datagrams
The default of 16 is pretty low, let's bump this to accomodate for more queued datagrams. This is useful for AF_UNIX/SOCK_DGRAM logging and sd_notify() sockets as this allows queuing more datagrams before things start to block, thus improving parallelization and logging performance.
