Check that "?.struct_ops" and "?.struct_ops.link" section names define
struct_ops maps with autocreate == false after open.

selftests/bpf: Verify struct_ops autoload/autocreate sync2024-03-06T23:18:15ZEduard Zingerman2024-03-06T10:45:23Zurn:sha1:651d49f15b2a84b3bcfe950fa99c3672b9619dbd
Check that autocreate flags of struct_ops map cause autoload of
struct_ops corresponding programs:
- when struct_ops program is referenced only from a map for which
autocreate is set to false, that program should not be loaded;
- when struct_ops program with autoload == false is set to be used
from a map with autocreate == true using shadow var,
that program should be loaded;
- when struct_ops program is not referenced from any map object load
should fail.

Check that bpf_map__set_autocreate() can be used to disable automatic
creation for struct_ops maps.
