073fe18edf [ossfuzz] Fix parallel builds 
With `make -j` multiple builds of `standaloneengine.o` happened in
parallel. Fix this by detecting `standaloneengine.o` and moving it to a
depedency.

3c40db8d25 [ossfuzz] Improve the fuzzers 
* Run more decompression variants
* Round trip the compression fuzzer and do partial decompression as well
* Add a compression fuzzer that compresses into a smaller output buffer
  and test the destSize variant

These fuzzers caught 2 bugs that were fixed in the previous commit.
* Input buffer over-read in partial decompress
* Partial decompress fails if output size is 0
