Do not specify fully versioned arch-specific requires for noarch packages

The Packaging:Guidelines#Requiring_Base_Package explicitly prohibits this
by:

    When a subpackage requires the base package, it must do so using
    a fully versioned arch-specific (for non-noarch packages) dependency.
                                         ^^^

Addressing:
BuildError: mismatch when analyzing openscap-content-sectool-0.9.13-5.fc21.noarch.rpm, rpmdiff output was:
