Don't install ghub-pkg.el as it isn't necessary.

Build succeeds with 13.0-RELEASE amd64.

Can you share more info about why we switched from the original method?
*.el* also matches forge-pkg.el. But it is only used to create package for ELPA and unnecessary for FreeBSD port/package. So I changed way to install so forge-pkg.el isn't installed.
