cmake-qemu.bbclass: make it more usable

Browse Source 
Make the cmake-qemu.bbclass more usable:
- Drop the CMAKE_EXEWRAPPER_ENABLED variable (which does not make much
  sense without the second commit of the original patch series).
- Inherit qemu to make the cmake-qemu a drop in replacement for cmake.

# Not all platforms are supported by Qemu. Using qemu-user therefore
# involves a certain risk, which is also the reason why this feature
# is not activated by default.
# is not part of the main cmake class by default.
#
# One use case is the execution of cross-compiled unit tests with CTest
# on the build machine. If CMAKE_EXEWRAPPER_ENABLED is configured,
# cmake --build --target test
# works transparently with qemu-user. If the cmake project is developed
# with this use case in mind this works very nicely also out of an IDE
# configured to use cmake-native for cross compiling.
