packagegroup-gumstix: build qt4e packages

QT4 Embedded enables QT apps to write directly to the framebuffer
rather than relying on a windowing system like X11---rather handy for
embedded applications.  As such, we pull this packagegroup into the
gumstix packagegroup so these packages get built by the Gumstix
Buildbot [1] and made available through the package repository [2].

eglinfo: Add support for eglinfo-(fb|x11)

This utility has previously been packaged with the SGX package but as
this is a standalone, generically useful utility, we pull in this one
instead.
