feat(lib): profiles: more portable load-path/Info-directory-list

Browse Source 
The Emacs appimage generates a new mountpoint on each invokation, but
Doom's profiles assume that the Emacs directories don't move. To make
Doom's profiles a little more profile, it will no longer set `load-path`
and simply add the new paths to the existing one. Same for
Info-directory-list.

Consequently, this also seems to speed up startup times for ~8% in my
tests. Neat.
