This fixes a regression from bug 1258341 where the eslint binary no longer
gets run from a shell on msys. Without this, a WindowsError [Error 139] is
thrown.

This integrates 'eslint' with the mozlint framework. The old |mach eslint| command is kept around
for backwards compatibility and will simply dispatch to |mach lint|. But |mach lint| should be
preferred as the old command may eventually be removed.
The old |mach eslint| command should be mostly backwards compatible with a few exceptions:
1. Can no longer define --extensions on the command line, this is instead hardcoded into
eslint.lint.
2. No longer using eslint formatters. However, the default mozlint formatter should be
identical to the default eslint formatter, so developers should not notice a change.
This does mean that non-default eslint formatters can no longer be used unless a mozlint
copy of them is created.
3. Installs dependencies automatically without prompting the user. This was necessary due to
python multiprocessing limitations, but is actually also a better UX. Because the npm
dependencies aren't global anymore, there isn't really any reason *not* to install them
automatically.
Apart from that, any difference from the old |mach eslint| I'd consider a bug.
The main eslint implementation now lives in tools/lint/eslint.lint instead of
tools/lint/mach_commands.py.
