Ignore requirements of -doc packages when checking for misnamed

[irushchyshyn]

Documentation packages usually have:

Requires:   %{name} = %{version}-%{release}

which makes them require python- named package. But this should not be a problem when we switch python- to mean python3- in names.
E.g. see python-paramiko, it is misclassified as Misnamed requires due to this.

This PR makes sure the -doc package requirements are ignored when checking for misnamed requirements.
