selftest/reproducible: Drop rawlogs

The "rawlogs" data consists of a long string of results data which is
already in a structured data format. I can't see this is adding much
value in duplciating the data but it does create a huge string with a
lot of long problematic pathnames and inflates the results data size.

I suggest we drop this data as obsolete and not necessary.
