app-laptop/tp_smapi: new version 0.42.

This adds a new version 0.42, and updates the ebuild a bit.

First, the ebuild was updated to EAPI=6. Then the RESTRICT=userpriv
was removed, as it no longer seems to have any effect: I can install
the package fine with FEATURES=userpriv. Next, an obsolete kernel
version check was removed. Every version of every flavor of Linux
sources we have in the tree is already newer than 2.6.19. Finally,
einstalldocs (from EAPI=6) was used to install the current set of docs
as well as a TODO that had been omitted.

I have added myself as the maintainer of this package, since I still
have hardware that it supports.
