core: Change last_seen_bit to uint32_t in class__find_holes()

And it is being compared against uint32_t variables, resulting in this
clang warning:

  /var/home/acme/git/pahole/dwarves.c: In function ‘class__find_holes’:
  /var/home/acme/git/pahole/dwarves.c:1439:43: warning: comparison of integer expressions of different signedness: ‘int’ and ‘uint32_t’ {aka ‘unsigned int’} [-Wsign-compare]
   1439 |                         if (last_seen_bit < aligned_start && aligned_start <= bit_start) {
        |                                           ^

Since it can't be less than zero, just make then uint32_t.
