Performs an explicit check for sys/un.h with the appropriate #includes.

I freely confess that this is one of the most bizarre things I have
ever seen. Android's sys/un.h header uses sa_family_t in the
sockaddr_un struct but neither defines it nor includes a header that
does.

This leads to the following warning when running ./configure:

  configure: WARNING: sys/un.h: present but cannot be compiled
  configure: WARNING: sys/un.h:     check for missing prerequisite
headers?
  configure: WARNING: sys/un.h: see the Autoconf documentation
  configure: WARNING: sys/un.h:     section "Present But Cannot Be
Compiled"
  configure: WARNING: sys/un.h: proceeding with the compiler's result
  configure: WARNING:     ##
------------------------------------------- ##
  configure: WARNING:     ## Report this to
openssh-unix-dev at mindrot.org ##
  configure: WARNING:     ##
------------------------------------------- ##

Thankfully this struct is defined in sys/socket.h. I have attached a
patch that explicitly runs AC_CHECK_HEADERS with the appropriate
parameters to ensure sys/un.h is detected properly. No actual source
code needed to be modified.
