oeqa/runtime/microcode: Enable microcode update test

Browse Source 
With iucode-tool, identified the selected microcode to be used for
microcode update by the specific processor. Compared the updated
microcode from dmesg to the selected microcode, test failed if the
updated microcode revision does not match the available selected
microcode revision from the iucode-tool. Compute int from hexadecimal
for comparison based on Naveen Kumar suggestion.
