Update Module-Metadata to CPAN version 1.000022

  [DELTA]

1.000022 - 2014-04-29
  - work around change in comparison behaviour in Test::More 0.95_01 by being
    more explicit with our tests - now explicitly checking the string form of
    the extracted version, rather than the entire version object
  - ensure the extracted version is returned as a version object in all cases
    (RT#87782, Randy Stauner)

1.000021 - 2014-04-29
  - fix use of newer interface from File::Path, to avoid another prereq on
    older perls (Graham Knop, PR#7)
  - fixed all out of date prereq declarations

1.000020 - 2014-04-27
  - new is_indexable() object method (ether, RT#84357)
  - eliminated dependency on IO::File (and by virtue, XS) - thanks, leont!
  - removed cruft in test infrastructure left behind from separation from
    Module::Build (ether)
  - repository moved to https://github.com/Perl-Toolchain-Gang/Module-Metadata
  - .pm file is now wholly ascii, for nicer fatpacking (RT#95086)
  - some code micro-optimizations (Olivier Mengué, PR#4)
