Subject: [PATCH] Relax dpkg version regex

For non-release builds the version will include the number of commits since last release and the commit hash with dashes, e.g. 1.20.8-46-g0881.
For downstream distros it seems it may include their identification strings, e.g. 1.20.9ubuntu2.

Make the regex match everything after the version number to avoid incorrectly erroring on such versions.

Fixes #18
