Set working directory for Elvis linter (#4726)
Most of the time it works to assume that the current working
directory is the root of the project.  However, this is not the case
for Rebar3 checked out dependencies, for example.

It's also worth noting that because of the way Elvis handles file
patterns, and because directories in configuration are relative to the
project root, the path supplied to command must be also relative.
