Leon Hwang 3808171428 libbpf: Avoid unnecessary mmap resize for percpu data maps ...

Use array_map_mmap_sz() for PERCPU_ARRAY like ARRAY in bpf_map_mmap_sz().
This lets bpf_map__set_value_size() skip mmap(), memcpy(), and munmap()
when the old and new value sizes occupy the same number of pages.

Fix some typos btw:

* mmapble -> mmapable
* satisified -> satisfied
* relocatin -> relocation
* atach_btf_obj_fd -> attach_btf_obj_fd
* len_secnd -> len_second
* precendence -> precedence
