tools/syz-execprog: create coverage file per program run
When coverfile option is used with multiple program inputs (e.g., with
a corpus input), syz-execprog overwrites the output coverage files with
each program run.
Create coverage file per program run instead, which would let save
the coverage information for all inputs.
