www/py-yt-dlp-ejs: Remove the IGNORE line

This do-fetch target does not repackage anything.
It fetches the tarball, extracts it, then fetches NodeJS dependencies
into the same folder, and packages this folder as a final tarball
used during build.

AFAIK there is nothing wrong with this port the way it is now.

This can't be done in post-extract due to internet access that is
required.
