build: don't embed beautifier plugin

The beautifier plugin does not currently know how to access embedded
resources, and when embedding it, we get a different data_dir back from
libpeas.

So for now, lets just not embed the plugin and once that is all fixed,
we can change it to use embedded plugins.
