tools: rely on the libinput and quirks tool to pick the right directories

Don't use a custom hack here, just make sure the tool ends up in the builddir
so it's picked up by the libinput main tool.

This means the PATH isn't set up correctly when called directly
(./builddir/libinput-measure-touchpad-pressure) but the workaround is to
always use the libinput tool - just as we expect from users.

To make it more obvious that we're not supposed to run this directly, rename
the source file to .py
