resulttool: Improve repo layout for oeselftest results

Having all oe-selftest results on top of each other results in a large 640MB
json file which is hard to use. Split the results out per machine and test type.

This also stops the toolchain raw logs from overwriting each other meaning more
than one MACHINE is preserved.
