selftests/bpf: Add tests for sdiv/smod overflow cases
Subtests are added to exercise the patched code which handles
- LLONG_MIN/-1
- INT_MIN/-1
- LLONG_MIN%-1
- INT_MIN%-1
where -1 could be an immediate or in a register.
Without the previous patch, all these cases will crash the kernel on
x86_64 platform.
Additional tests are added to use small values (e.g. -5/-1, 5%-1, etc.)
in order to exercise the additional logic with patched insns.
