python-mako: Re-import host-only package from abandoned packages repo

Mako was removed in 60ce07b9a1d5c7a53297f177f10af68f3304be9e; at the
time we were using host pip to install host Python packages and so
having this package was not necessary.

With the move away from host pip and toward proper host packages, it
would be better to have a Mako host-only package here to support the
mesa package in the video feed.

This re-imports the package from the abandoned packages feed, updates
the makefile with current Python package conventions, and updates the
package to the latest version.

+define Package/python3-mako/description
+Mako is a template library written in Python. It provides a familiar,
+non-XML syntax which compiles into Python modules for maximum
+performance. Mako's syntax and API borrows from the best ideas of many
+others, including Django templates, Cheetah, Myghty, and Genshi.
+Conceptually, Mako is an embedded Python (i.e. Python Server Page)
+language, which refines the familiar ideas of componentized layout and
+inheritance to produce one of the most straightforward and flexible
+models available, while also maintaining close ties to Python calling
+and scoping semantics.
