sci-libs/dlib: Version bump to 19.9

From donat-b on GitHub, with thanks.
Apologies for strange commit style, this is due to GitHub tooling issues.
Have had to pull the raw files out as the diff is broken. Somehow.

Closes: https://github.com/gentoo/gentoo/pull/7207
Package-Manager: Portage-2.3.40, Repoman-2.3.9
