fuzz: Remove peepmatic fuzz targets

There are occasional timeouts in type checking where Z3 hangs. This is a known
issue[0] with the implementation of type checking in Peepmatic, and getting
these timeouts in the fuzzers is just annoying and adds noise to our fuzzing
results. When we fix [0] we can reintroduce these fuzz targets.
