brew/Library/ENV/scm/git, branch master 🍺 The missing package manager for macOS ENV: move to new paths.

We never needed the "separate shims for separate versions" functionality and it just adds confusion. - Move `Library/ENV/pkgconfig` to `Library/Homebrew/env/pkgconfig` to get more things under `Library/Homebrew` - Move `Library/ENV/scm` to `Library/scm` as these wrappers are not actually used by or related to superenv (or stdenv) in any way.

Print path of first detected Git instead of executing it. This is hidden
behind a `--homebrew=print-path` argument that is unlikely to conflict
with any existing or future Git flags.

scm/git: prevent exec bomb with 'env :userpaths'

Using `git` from `Formula#install` can cause an exec bomb if used in a
formula with `env :userpaths` because that causes both `Library/ENV/4.3`
and `Library/ENV/scm` to be in PATH, both of which contain a `git`
binary that is the same SCM wrapper. Those will mutually exec each other
indefinitely as they fail to detect that they are the same wrapper.

Extend the exec-bomb protection to check the paths after all symbolic
links have been expanded to prevent this situation.

Fixes #43.
Fixes Homebrew/homebrew-core#133.
Fixed Homebrew/homebrew-core#143.

Closes #46.

scm/git: handle no Xcode/CLT configuration

`/usr/bin/<tool>` will be a popup stub under such configuration.

The idea is to let `scm/git` to handle all of git location resolution
throughout Homebrew codebase.

We cannot really recover from this, but at least we'll provide a clearer
error message than trying to call `exec` with an empty string.

ENV: protect against RUBYLIB/RUBYOPT

Some things can break in hard to debug ways if users or build scripts
set these variables, causing our otherwise quite robust Ruby wrappers
to fail. In theory, we could also use `--disable-rubyopt`, but this is
not supported in Ruby 1.8 (and we still care about it).

Use the same interpreter for the shims that is also used to run the main
Homebrew process (the one invoked via `brew`). The magic basically lies
in executing `ruby` with the `-x` option (supported since at least 1.8)
and in the following shebang line.
