06fca841fb selftests/bpf: Use __BYTE_ORDER__ 
Use the compiler-defined __BYTE_ORDER__ instead of the libc-defined
__BYTE_ORDER for consistency.

487ef148cf selftests/bpf: Switch to new btf__type_cnt/btf__raw_data APIs 
Replace the calls to btf__get_nr_types/btf__get_raw_data in
selftests with new APIs btf__type_cnt/btf__raw_data. The old
APIs will be deprecated in libbpf v0.7+.

7a2fa70aaf selftests/bpf: Add remaining ASSERT_xxx() variants 
Add ASSERT_TRUE/ASSERT_FALSE for conditions calculated with custom logic to
true/false. Also add remaining arithmetical assertions:
  - ASSERT_LE -- less than or equal;
  - ASSERT_GT -- greater than;
  - ASSERT_GE -- greater than or equal.
This should cover most scenarios where people fall back to error-prone
CHECK()s.

Also extend ASSERT_ERR() to print out errno, in addition to direct error.

Also convert few CHECK() instances to ensure new ASSERT_xxx() variants work as
expected. Subsequent patch will also use ASSERT_TRUE/ASSERT_FALSE more
extensively.

Add selftests juggling endianness back and forth to validate BTF's handling of
endianness convertions internally.
