brew.sh: reorder to speedup shellenv.
Reorder and restructure this file to make it as fast as possible for e.g. `brew --prefix`. Once we have that, also give `brew shellenv` short-circuit command execution to make it as fast as possible. On my machine (with a warm cache) this gets: ``` brew shellenv 0.01s user 0.03s system 100% cpu 0.038 total ``` Compared to: ``` brew shellenv 0.09s user 0.19s system 100% cpu 0.277 total ``` before this commit.
