The three test functions share the same algorithmic structure:
set up ACL with full permissions for an entry type, verify
access is granted with mask=rwx, clear the mask, verify
access is denied. They differ only in the ACL entry type
(ACL_USER / ACL_GROUP / ACL_GROUP_OBJ) and the UID/GID
used.

Could these be collapsed into a single parametrized test
function driven by a struct tcase array? Something along
the lines of:

  struct tcase {
      uint16_t tag;
      uid_t uid;
      gid_t gid;
      uid_t owner_uid;
      gid_t owner_gid;
      const char *desc;
  } tcases[] = {
      {ACL_USER, USER3_UID, USER3_GID,
       TEST_UID, TEST_GID, "ACL_USER with mask"},
      {ACL_GROUP, USER2_UID, USER2_GID,
       TEST_UID, TEST_GID, "ACL_GROUP with mask"},
      {ACL_GROUP_OBJ, USER2_UID, USER2_GID,
       TEST_UID, USER2_GID, "ACL_GROUP_OBJ with mask"},
  };

That would remove roughly 130 lines of duplicated logic and
make the data-driven pattern explicit.

Verdict - Needs revision
