erroneous links in calltree to coverage files

[DavidKorczynski]

Several of the callsite links in the Tarantool calltree link to wrong files

[DavidKorczynski]

This is because we extract links by way of the project profile rather than the fuzzer profile:

fuzz-introspector/post-processing/fuzz_analysis.py

Lines 127 to 131 in afa6c4e

	for fd_k, fd in project_profile.all_functions.items():
	if fuzz_utils.demangle_cpp_func(fd.function_name) == parent_fname:
	callsite_link = coverage_url + "%s.html#L%d" % (
	fd.function_source_file, # parent source file
	node.src_linenumber) # callsite line number

This means links in functions with same name but different implementation (e.g. LLVMFuzzerTestOneInput) will have wrong links.
