kqueue: open watched directories with close-on-exec flag

Browse source 
[FreeBSD and OpenBSD contributors clarified that O_CLOEXEC has been
supported for ~ 2 years on both, so for the moment we're assuming
that every platform with kqueue also has working O_CLOEXEC. Please reopen
the bug, with a tested patch that uses _dbus_fd_set_close_on_exec() instead,
if this assumption turns out to be false. -smcv]
