[opus] [PATCH] genversion.bat: generate same version as update_version

[Ricardo Constantino]

Remove version.mk and references to it in the repo.

genversion.bat will now generate the same version strings as
update_version script, i.e. without 'v' prefix, without a fallback
if git archive is used.If run from a release tarball it'll use
package_version file, like configure. If run from a git repo, it
will use the same 'git describe' with '-dirty' as update_version.
---
If there's supposed to be a fallback for git archives, it should
be used by both genversion.bat and update_version.
