.github: add scant_fuzzer.yml build

marc-hb · lgirdwood · commit e27cb456639b · 2021-05-03T09:31:00.000+01:00
This is NOT how to properly compile the fuzzer, this is only to detect earlier and faster problems like thesofproject#3824 (288e228) and thesofproject#4118 (758e7be) In other words, when reverting the oss-fuzz parts of either of these commits this build fails as desired.
