tools/syz-cover: allow for exporting source line coverage info
Add a `json` CLI flag that allows for writing out a JSON file with the
following coverage information.
* Module
* Filename
* Covered source lines
* Uncovered source lines
* Both source lines
This can be used to view syzkaller coverage information on other source
browsing/viewing tools.
Usage:
$ ./syz-cover -kernel_obj <path/to/vmlinux> -json <output_json> rawcover
