server: don't complain if setsockopt(SO_PRIORITY) call fails

Browse Source 
dc7855967f did this for the TCP_NODELAY and IP_TOS calls; we should do
it for priority as well if necessary.

We also #ifdef the setting of the low-level socket priority based on
whether we have a definition of SO_PRIORITY available. This option is
not available on Illumos/Solaris platforms; however, since we set IP_TOS
anyway it is not a big deal to omit it here.
