udev-detect, alsa-card: Adopt avoid resampling option from daemon.conf

Browse source 
Previously, the "avoid-resampling" option of daemon.conf is to make the
daemon try to use the stream sample rate if possible for all sinks or
sources.

This patch applies this option to module-udev-detect and module-alsa-card
as a module argument in order to override the default value of daemon.conf.

As a result, user can use this argument for more fine-grained control.
e.g.) set it false in daemon.conf and set it true for module-udev-detect
or a particular module-alsa-card in default.pa.(or vice versa)

To set it, use "avoid_resampling=true or false" as the module argument.
