stepmania: fix build with gcc 12, ship ffmpeg 2.1.3 with distfiles

If ffmpeg with specific version is not present in the work source
directory, cmake attempts to clone its repository with git and
check out version 2.1.3. This approach presents two issues:

1. It can no longer be cloned using git:// for github (see
https://github.com/stepmania/stepmania/pull/2200) which results in
connection timeout and build failure as the result.

2. Downloaded tarball is erased after successful build since it is
considered to be part of the source code.
Its retrieval and storage for future use should be done by xbps-src.
