dev-go/licenseclassifier: new ebuild

I find this tool very helpful for managing LICENSE in different
ebuilds. Just run identify_license on any file - just a source
code or COPYING/LICENSE file. It also can be built against
licenses in /var/db/repos/gentoo/licenses, but this is not yet
implemented in this commit.

+    The license classifier is a library and set of tools that can analyze text
+    to determine what type of license it contains. It searches for license texts
+    in a file and compares them to an archive of known licenses.
+    These files could be, e.g., LICENSE files with a single or multiple licenses in it,
+    or source code files with the license text in a comment.
