build: Simplify config file setup

Browse Source 
This introduces no functional changes, just simplifies the code.

As described in the meson manual
(https://mesonbuild.com/Configuration.html#configuring-without-an-input-file),
passing `false` to `configuration_data.set()` will cause the specified
value to be `#undef`fed. Passing `true` will cause it to be defined to
1.
