orinoco-conf: remove dependencies of update-modules
Since update-modules became obsolete, no need for these dependencies.
Also:
* install the conf files in the modprobe.d directory. /etc/modutils is
also obsolete;
* remove postinst/postrm scriptlets since they ran update-modules and
this is just an alias file;
