convert: .hgtags files contain SKIP lines (issue3736)

convert is writing SKIP lines into the various .hgtags files when a
tag corresponds to a revision marked to be skipped in the conversion
(e.g. with filemap).  These lines should only be maintained in the
shamap file, not in the .hgtags (where they emit unhelpful warnings).
Minimal patch to ignore SKIP lines when updating the .hgtags files.
