Issue Description

OBS has a new feature using the OBS:AnityaDistribution attribute, which checks upstream versions and fetches the version of a package from the .spec file. It's very helpful.

Where the package uses OBS services to fetch new sources and set the package version at build time, the spec file version remains the same, so OBS detects the wrong package version.

Expected Result

Correct version of package detected

How to Reproduce

1. Use _services file to fetch sources
2. Use <service name="set_version" mode="buildtime" />
3. Use AnityaDistribution attribute
