mako should be in packages/bin

[sfc-gh-sgwydir]

This change adds mako to the build/packages/bin directory with all the other binaries when running cpack, which is useful for automation.

As a side effect this adds mako to the foundationdb-clients packages. I'd like to get some feedback on whether or not this is desirable for other users or we should create a third package with tools, or just not package mako at all.
