Subject[PATCH v2 3/7] libbpf hashmap: Fix signedness warnings
From
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++) \
