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
