[PATCH i-g-t v1 2/4] lib/igt_core: Added message to runner about ignoring kernel warns

[Kamil Konieczny]

Allow a test to emit regex into dmesg to be read by runner when
it will be generating results based on kernel dmesg. When it
will encouter such message, it will save it and then temporarily
ignore kernel warnings or errors which matches given regex.
