Update to 0.05
    
    - New upstream release 0.05
      - Add pure-perl implementation for situations where neither ${^GLOBAL_PHASE}
        nor XS are available
    - This release by DOY -> update source URL
    - BR: perl(XSLoader) only if we're doing an XS build, and in that case add a
      runtime dependency on it and BR: perl(ExtUtils::CBuilder) ≥ 0.27 too
    - Add runtime dependency on perl(Carp)
    - Drop %defattr, redundant since rpm 4.4
