libbpf: Add missing LIBBPF_API annotation to libbpf_set_memlock_rlim API

[ Upstream commit 93ee1eb8 ]

LIBBPF_API annotation seems missing on libbpf_set_memlock_rlim API, so
add it to make this API callable from libbpf's shared library version.

Fixes: e542f2c4 ("libbpf: Auto-bump RLIMIT_MEMLOCK if kernel needs it for BPF")
Fixes: ab9a5a05 ("libbpf: fix up few libbpf.map problems")
