Mako: Remove package

Mako: Remove package

This package (more specifically, the host version) was added for mesa in
the video feed[1]; no packages in the packages feed require this
package.

As mesa will be updated to install Mako using host pip[2], there is no
need to continue maintaining the package here. It will be imported into
the abandoned packages repo[3].
