cmake: support OpenEmbedded Qt4 tool binary names

The FindQt4 module looks for Qt4 binaries to be able to gather the
paths used for compilation and also to be using during other processes
(translation update, translation binary generating and like) however
OpenEmbedded has renamed those to allow old QMake to be used in
parallel with the current one. This patch adds support for the
OpenEmbedded specific binary names.

Upstream-Status: Inappropriate [embedded specific]
