audio/mscore fetch MuseScore_General_* files as DISTFILES

I noticed that musescore build always downloads MuseScore_General_* files,
and it takes a long time since download site was slow.
How do you like fetching them as DISTFILES to shorten build time ?

I intentionally left the downloading VERSION file from the site,
that is because we can tell if the download site VERSION is updated
after fetching it as local distfiles.

This diff brings no package change and I didn't increment REVISION.

ok?
