[Buildroot] [git commit] package/libedit: switch to alternate URL for proper packaging

commit: http://git.buildroot.net/buildroot/commit/?id=dc2a13a2aa30b0fd9006c2a7c2103f5af2bf00a7
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Upstream libedit does not have a proper homepage, and does not provide
any sort of packaging whatsoever. So far, we used Debian's wayback
machine to get a tarball of a rather oldish libedit.

As Thomas pointed out, someone has been maintaining a proper autotools
based, up-to-date package for a while.

While Debian is stuck to 2.11 (5 years old now), we bump to 3.1 as a bonus.

Remove our libedit.pc, it's now bundled with the package.
