bpf: allow any program to use the bpf_map_sum_elem_count kfunc
Register the bpf_map_sum_elem_count func for all programs, and update the map_ptr subtest of the test_progs test to test the new functionality.
The usage is allowed as long as the pointer to the map is trusted (when using tracing programs) or is a const pointer to map, as in the following example:
struct { __uint(type, BPF_MAP_TYPE_HASH); ... } hash SEC(".maps");
...
static inline int some_bpf_prog(void) { struct bpf_map *map = (struct bpf_map *)&hash; __s64 count;
count = bpf_map_sum_elem_count(map);
... }

selftests/bpf: Remove SEC("version") from test progs
Since commit 6c4fc209fcf9d ("bpf: remove useless version check for prog load") these "version" sections, which result in bpf_attr.kern_version being set, have been unnecessary.
Remove them so that it's obvious to folks using selftests as a guide that "modern" BPF progs don't need this section.

Remove rlimit-based accounting infrastructure code, which is not used anymore.
