Remove duplicated info.yml and services.yml files

I messed up the default fork branch, so here is a patch.

It seems that the 1.2 and 1.3 versions have been created from a branch that has the fix, but the 1.4 branch including the D9 fixes are in a different branch that has derived from the branch used before.

The easiest way is probably to do
$ git checkout 8.x-1.x
$ git merge 8.x-1.4
$ git push origin 8.x-1.x

Which would cause the D9 fixed to be correctly merged in the main branch.
