selftests/bpf: precision tracking test for BPF_NEG and BPF_END
As seen from previous commit that fix backtracking for BPF_ALU | BPF_TO_BE
| BPF_END, both BPF_NEG and BPF_END require special handling. Add tests
written with inline assembly to check that the verifier does not incorrecly
use the src_reg field of BPF_NEG and BPF_END (including bswap added in v4).
