glib-unix: Don't fall back from O_NONBLOCK to O_NDELAY

Browse Source 
Since 5c65437d "glib-unix: Add O_NONBLOCK support to g_unix_open_pipe()"
we have been using O_NONBLOCK unconditionally, so we might as well drop
the fallback here as well. This commit should be reverted if someone
reports a significant/supported platform that genuinely doesn't have
O_NONBLOCK.
