[PATCH v3 3/7] libbpf hashmap: Fix signedness warnings

[Ian Rogers <irogers@xxxxxxxxxx>]

Fixes the following warnings:

hashmap.c: In function ‘hashmap__clear’:
hashmap.h:150:20: error: comparison of integer expressions of different signedness: ‘int’ and ‘size_t’ {aka ‘long unsigned int’} [-Werror=sign-compare]
  150 |  for (bkt = 0; bkt < map->cap; bkt++)        \

hashmap.c: In function ‘hashmap_grow’:
hashmap.h:150:20: error: comparison of integer expressions of different signedness: ‘int’ and ‘size_t’ {aka ‘long unsigned int’} [-Werror=sign-compare]
  150 |  for (bkt = 0; bkt < map->cap; bkt++)        \
