tools/syz-execprog: use more precise addresses when collecting coverage
Make two improvements to addresses obtained from kcov:
- call backend.PreviousInstructionPC() so that they point to the
__sanitizer_cov_trace_pc calls;
- read the top 32 bits of the kernel addresses from /proc/kallsyms
instead of using the hardcoded 0xffffffff value
