selftests/bpf: Enable timed may_goto tests for LoongArch
Enable stream_cond_break, may_goto_interaction, and verifier_may_goto_1
tests for LoongArch, aligning with recent architectural infrastructure
support (timed may_goto and arch_bpf_stack_walk JIT).
With this patch, the following tests passed on LoongArch:
sudo ./test_progs -a stream_success/stream_cond_break
sudo ./test_progs -a verifier_bpf_fastcall/may_goto_interaction
sudo ./test_progs -a verifier_may_goto_1
