In some refactoring work deviceinfo_bootimg_qcdt and
deviceinfo_bootimg_qcdt_type were accidentally renamed to just
deviceinfo_qcdt{,_type}. Change back to original name everywhere.
Among the notable changes is that we modify the bootimg header_v2 test
so that bootimg_qcdt="false" is acceptable in the deviceinfo. I am not
sure why it was added to the !expected substrings, we have plenty of
header_v2 devices with the property set.
