- handle hash in url of slapos.recipe.build:download
  A hash there is instruction to verify checksum of the tarball, not
  part of the real URL.

- fix namever to detect that '-Country' is not version suffix.

Before this patch BOM entry for GeoLite2-Country was emittted as:

    GeoLite2                     Country.tar.gz#dc6224c648350d90f344a0c5c3ca5474 http://geolite.maxmind.com/download/geoip/database/GeoLite2-Country.tar.gz#dc6224c648350d90f344a0c5c3ca5474

Noticed while computing BOM(Re6stnet).
