Update to 1.122
    
    - New upstream release 1.122
      - Now requires PPI-1.218, which has numerous enahncements and bug fixes
      - Also now requires Readonly-2.00, which obviates the need for Readonly::XS
        to get fast constants
      - File::HomeDir, File::Which, and Term::ANSIColor are all required now
        instead of being optional or recommended; this simplifies our test code
        and ensures consistent optimal behavior for all users
      - Added two new policies: BuiltinFunctions::ProhibitUselessTopic and
        RegularExpressions::ProhibitUselessTopic
      - Updated the perlcritic.el script to use modern Emacs hooks (GH #556)
      - Removed all the internal RCS keyword boilerplate blocks that were never
        getting expanded
    - Use %license where possible
    - Drop upstreamed patches
