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.
