959eec1fdd changed the message
to show the local username with "$user" but this is not always set.
Some systems will have USER/USERNAME/LOGNAME, so just use "whoami"
instead.
This avoids diffs being applied in the work tree to files that are
supposed to be excluded (clang tests), allows arc to properly provide
interactive feedback for the formatting fixes, and reduces the number of
files that we format, in a change affecting N files, from N^2 to N.
Summary:
The only guarantee there seems to be in the clang-format packaging is
that an executable called `clang-format` is in the PATH. Use the
in-tree `clang-format-diff.py` to avoid assuming anything else.
Also remove dead code for SVN repo and switch to `git diff-index` which
is the git plumbing equivalent of `git diff` in this case.

D49116 was using clang-format-diff because at the time of its writing,
it needed to handle the subversion repo as well.

Summary:
This uses clang-format-diff as a linter for Arcanist.
`arc lint` flow, also run as part of `arc diff` unless skipped with
`--nolint`, will now run the linter shell script on the changed files,
and prompt the user to accept the suggested changes.
