I really don't like this commit, but import() is currently breaking
our publish script.
When "normal" tests we are transpiling import() so that it works
with Jest. We can't do it while publishing because we need to
publish the untranspiled import() so that it can load real .mjs files.

Since these were getting left in, things that loaded the config, and then passed in back to Babel would get `test` and such _twice_, which could lead to either bad configuration merging, or no configuration at all if the patterns were relative to different directories, as was the case in https://github.com/babel/babel-loader/issues/642.

Currently the `opts.filename` value exposed to plugins is just whatever the user passed. While it _could_ be relative to the working directory, if Babel was passed an absolute URL, it'll be absolute.
This PR explicitly ensures the filename is a relative path based on the working directory. This also exposes an officially endorsed API for reading the working directory path.
