Change default rpmlint configuration file
    
    Current rpmlint configuration file (.rpmlint) is hidden. Making the file
    visible may encourage packagers looking at other repositories to
    properly configure rpmlint runs and omit false positives. This commit
    makes <module_name>.rpmlintrc the default configuration file and
    triggers a deprecation message whenever a .rpmlint file is implicitly
    used.
