tar: avoid strtoul().

This is part of the general trend to prefer signed integer types,
to allow better runtime checking with -fsanitize=undefined etc.

  * (struct tar_stat_info): ue intmax_t, not unsigned, for sparse major
    and minor.
  * (tar_sparse_major): likewise.
  * (tar_sparse_minor): likewise.

Sync with GNU tar 4642cd04edbd57414e004920fa4976d9f3be6206.
