pax-utils: upgrade to 0.2.1

- update metadata. license checksum is skipped, as pax-utils is depended by do_package task itself.
  I.e. the 1st do_package will be run after pax-utils-native is built. So far checksum verification
  is included in do_package task
- no need to override {S} since {S} uses {BPN}
- no need to define "_GNU_SOURCE" which has been included by source
  tar ball. Also remove do_compile override accordingly
- remove recipe internal md5sum, which is not used by Poky
