protocol-native: compare uint64_t variable with (uint64_t) -1 instead of (size_t) -1 for compat with 32bit archs

Instead of trying to re-execute pulseaudio itself with LD_BIND_NOW set,
just find the correct flag for the linker to request immediate bindings
(all ELF files support that option), and use that when linking the daemon.

Reduce the amount of compiled and executed code as well.

This allows us to forward the fixed latency directly from the sink to
the monitor source withut having to wait for pa_sink_put().

This should close rhbz #494851, mandriva bz #51234.

Probably the same as our own #572, launchpad #352732.

This has the benefit that we can properly support ALSA devices where
only the raw 'hw' device exists but no 'front' although it's a proper
2ch stereo device.
