oeqa/runtime/parselogs: migrate ignores

Move the ignores from a huge dict in the parselogs.py module to .txt
files. This is just the common, tune, and qemu machine ignores; the
machine ignores that are not in oe-core will be added to the relevant
layers.

The list of ignores has not been reviewed in any meaningful way, this
should be done soon as I suspect a number of these are redundant.
