[Mono-winforms-list] Remove horrible MONO_MWF_USE_CARBON_BACKEND env vars

[Sebastien Pouliot]

Hey,

Hmm... it's a kind of hackish way to call (well marshal) uname
(sysname). It's worth a littl'comment IMO.

Otherwise I think it's a good idea to drop, by default, the need for an
environment variable :)
