Sanitize RPM names further

Both tilde and caret can show up in version numbers according to

  https://docs.fedoraproject.org/en-US/packaging-guidelines/Versioning/

However, bazel doesn't like these symbols and reports that

  workspace names may contain only A-Z, a-z, 0-9, '-', '_' and '.'

Luckily we already have code in place that deals with colon and
plus, so we simply need to extend it.
