selftests/bpf: Enable cpu v4 tests for LoongArch

Enable the cpu v4 tests for LoongArch. Currently, we don't have BPF
trampoline in LoongArch JIT, so the fentry test `test_ptr_struct_arg`
still failed, will followup.

Test result attached below:

selftests/bpf: Test ldsx with more complex cases

The following ldsx cases are tested:
- signed readonly map value
- read/write map value
- probed memory
- not-narrowed ctx field access
- narrowed ctx field access.

Without previous proper verifier/git handling, the test will fail.

If cpuv4 is not supported either by compiler or by jit,
the test will be skipped.
