pkg/cover, syz-manager: introduce the /cover?debug=1 parameter
Debugging coverage point validation warnings may require looking at
specific addresses, which are not printed anywhere. Add a URL parameter
that can be passed to prepareFileMap() to print a more meaningful error
message.
Also factor out the error message code from prepareFileMap() to reduce
its cyclomatic complexity.
