ruby: import from oldpackages and update to 2.1.2

This commit imports the old Makefile from old openwrt feeds.
Also, the package was updated to the latest version.

The new version was tested in a VM with no aparent problem.
No patches are needed.

I added myself as maintainer. If possible, I would like to gain
commit access.

Revert "xl2tpd: rename netifd protocol handler to l2tpv2 to avoid clashes with l2tpv3"

This reverts commit 981f2da45747df72c5ae2c45f265fe8f29af3d52.
OpenWrt wiki knew l2tp from l2tpv3tun, but luci knew l2tp from xl2tpd
