search_version: make version regex accept more after hyphen

This change allows the found version number to include additional
hyphens and periods after the first hyphen. This is needed to understand
`clang --version` in some older Ubuntu versions, which prints:

Ubuntu clang version 14.0.0-1ubuntu1.1

This logic also accepts any pre-release version following SemVer 2.0.0
syntax, bullet 9.
