Update to 0.034
    
    - New upstream release 0.034
      - Exceptions are now Path::Tiny::Error objects, not autodie exceptions; this
        removes the last dependency on autodie, which allows us to support Perls as
        far back as v5.8.1
      - BSD/NFS flock fix was not backwards compatible before v5.14; this fixes it
        harder
      - Lowered ExtUtils::MakeMaker configure_requires version to 6.17
