    window-x11: Fix _XOPEN_SOURCE usage for gethostname on FreeBSD
    
    On FreeBSD, gethostname is guarded by '__POSIX_VISIBLE >= 200112', which
    requires either '_POSIX_C_SOURCE >= 200112' or '_XOPEN_SOURCE >= 600'.
    Defining _XOPEN_SOURCE to 500 does not break the build because of
    implicit declaration, but it defeats the purpose of defining the macro.
