Subject: util/getversion,meson: Add script to allow version info with Meson

Add `util/getversion.sh` that retrieves version information from a
`versioninfo.inc` (what we use for releases) if present or uses
`util/getrevision.sh` if not.

Let Meson use it for flashrom's version. It seems Meson doesn't
generate the manual page at all, so the `--man-date` command is
currently unused.
