`Library/ENV` like `Library/Homebrew` is part of Homebrew basecode. It
should be able to be accessed during the `brew tests`.
By adding HOMEBREW_ENV_PATH variable, we allow test suit to locate these
codes.
The default HOMEBREW_LIBRARY_PATH should be
/usr/local/Library/Homebrew
not
/usr/local/Library/Homebrew/Homebrew

Currently HOMEBREW_BREW_FILE is a String, while other of HOMEBREW_*
variables are all Pathname. This commit unifies them all as Pathname,
so it will not cause any confusion.

Not sure why this is happening (beyond the Chef cookbook stupidly
deciding to not call through `bin/brew`) but fail and print a scary
looking error to hope to point people in the right direction.
