Create releases that don't require GNU Autotools during the build

biosdevname now uses Github releases which is awesome. However, tarball with the latest release (```biosdevname-0.7.3.tar.gz```) no longer contains generated ```configure``` script as it is (presumably) just ```git-archive``` export of the git tree.

This is fine but I still think that there is value in providing the tarball that doesn't require end users to install Autotools in order to build the package. After all, this is one of the few reasons why to continue using Autotools in 2018.
