Fixed “sendmsg() failed” alerts on HP-UX.

HP-UX needs \_HPUX\_ALT\_XOPEN\_SOCKET\_API to be defined to be able to  
use various POSIX versions of networking functions. Notably sendmsg()  
resulted in “sendmsg() failed (9: Bad file number)” alerts without it.

See xopen\_networking(7) for more details.
