oeqa/selftest/imagefeatures: Add testcase for fitImage

Browse Source 
This testcase generates the Image Tree Source and
the corresponding fitImage containing a kernel and
a ramdisk. It then checks if the these files exist
and if the right fields are present in the right
order in the Image Tree Source.

Tested with: oe-selftest -r  imagefeatures.ImageFeatures.test_fit_image

(From OE-Core rev: 97e986030ef33dbc43f8e18f7721b98ee381e29b)

Summary: Check if FIT image and Image Tree Source (its) are built
and the Image Tree Source has the correct fields.
Expected: 1. fitImage and fitImage-its can be built
2. The type, load address, entrypoint address and
default values of kernel and ramdisk are as expected
in the Image Tree Source. Not all the fields are tested,
only the key fields that wont vary between different
architectures.
