x11-themes/gtk-engines: migrate to lua-single.eclass

Builds, tests and installs fine even when built against lua5-4 so
support all PUC Lua versions currently in the tree.

Warning - as the ebuild stands now, USE=lua IS QUIETLY IGNORED for
non-native ABIs. The dependencies are ready for enabling it there as
well but since the pkgconfig wrapper lua-single.eclass sets up is not
multilib-compatible, it is necessary to patch upstream build scripts so
that they look for the pkgconfig module "${ELUA}" rather than just "lua"
- and for some reason running eautoreconf following the patching of
configure.ac resulted in corrupted test Makefiles. Pushing it as-is in
case the maintainers have got some idea on how to make this work, if not
will probably end up patching configure directly.
