cmus: fix configure checks against host files

cmuses configure checks an absolute path for the existence of a kernel
header. This results in a check against the hosts version of
/usr/include/sys/soundcard.h, which potentially does not exists (at
least on my system).

This patch supersedes http://patchwork.openwrt.org/patch/2713/.

cups: Update package source URL

The ftp.easysw.com site has disappeared completely.

This patch adds the official cups site as package source and
drops all easysw.com servers and not longer existent mirrors
of easys.com.
