* coverage: introduces llvm-cov-rel
Cf https://github.com/google/oss-fuzz/issues/6268
Latest clang-14 and clang-13 used by rust or swift have a slightly
different profraw file format
llvm-cov-rel is tool that will update the profraw file produced
by clang-13 to one readable by clang-14 llvm-cov tools
* Suricata as a rust project
* rust coverage: remaps every rust subdirectory in fuzz
So that projects not using default fuzz_targets subdir
get the good remap, and hence the good coverage report
