tweak: disable ahead-of-time native compilation

Browse source 
Rather than impose a 10-45min compilation step on users, I've disabled
ahead-of-time compilation for deferred compilation. In exchange, it will
eat up some CPU time the first time each uncompiled package is loaded,
but as this happens asynchronously (and are then quietly loaded in the
background), I think this is acceptable.

An --aot switch (or similar) will be added to `doom sync` and `doom
build` in the future, in case folks prefer the old behavior.
