Add VirtualE1000e NIC definition to the VIM mapping registry.

https://bugzilla.redhat.com/show_bug.cgi?id=1106924
The VirtualE1000e definition was introduced for VIM 5.0.
Instead of upgrading the whole VIM client to 5.5 and risking additional breakage,
updated the existing client to include the missing definition.
