pythondistdeps attempts to do invalid rich Provides (rpm 4.15.1 with backported fixes from master)

[Conan-Kudo]

When bootstrapping RPM 4.15.1 with pythondistdeps fixes backported in OpenMandriva Cooker, I've encountered the following bug:

BUILDSTDERR: error: No rich dependencies allowed for this type: (python3.8dist(createrepo-c) == 0.15.4)
BUILDSTDERR: error: No rich dependencies allowed for this type: (python3dist(createrepo-c) == 0.15.4)

I'm pretty certain the issue comes from 403f75c. It should be easily fixable...

When the list contains just one item, the parenthesis should not be there, correct?

[Conan-Kudo]

Yes, but also you're not allowed to do rich Provides at all

[ignatenkobrain]

but also you're not allowed to do rich Provides at all

… which would be so amazing, wouldn't it? :)

[hroncok]

oh, this is for provides?

[Conan-Kudo]

@hroncok Yep. But I'm pretty sure you can't do this exact thing on Requires either...

This is fixed with the merge of #982.
