package/libmodplug: update to git version

The libmodplug release has not been updated for over 5 years.
The git version contains many bug fixes, including for OOB
accesses, unaligned reads and writes, etc.

This git repository is the official home of libmodplug (by the original
author), however a new release does not seem likely anytime soon:
there are multiple open issues in the repository asking the author to
tag a release, all without a response.

Update buildroot to the current version of libmodplug from the official
git repository. The build system changed from autotools to cmake since
the last version.

We add a _CPE_ID_VERSION variable pointing to the latest stable
version, so that we don't get notified about all older CVEs that we
are not affected by.
