[OE-core] [PATCHv2] pseudo: use epoll API on Linux

[Trevor Woerner]

It doesn't make sense to carry these large patches against pseudo in
OE itself. Isn't pseudo one of the tools under The Yocto Project
umbrella? Adding patches to a recipe is what happens when upstream
isn't under our control, isn't responsive, or isn't cooperating.

Can someone volunteer to be the active maintainer of it and get commit
access? I'll volunteer, if nobody else does. But if I become the
maintainer, I'll need some time to get up-to-speed, or some potential
support from the current maintainer.
