package/libpjsip: disable remaining unspecified options

There are a bunch of options that are left unspecified; explicitly
disable them.

The epoll case is special: the configure script is broken, and will
enable it whether we pass --enable-epoll or --disable-epoll. But that's
OK because we prefer epoll over the alternative (select). So we do not
need to fix it. Which is nice becasue the configure.ac is named
aconfigure.ac (yes, with a leading 'a'), so it does not autoreconf
nicely... :-/
