Yuntao Wang	658d87687c	selftests/bpf: Fix return value checks in perf_event_stackmap test ... The bpf_get_stackid() function may also return 0 on success as per UAPI BPF helper documentation. Therefore, correct checks from 'val > 0' to 'val >= 0' to ensure that they cover all possible success return values.

Hengqi Chen	bd368cb554	selftests/bpf: Use BTF-defined key/value for map definitions ... Change map definitions in BPF selftests to use BTF-defined key/value types. This unifies the map definitions and ensures libbpf won't emit warning about retrying map creation.

Song Liu	1da4864c2b	selftests/bpf: Add callchain_stackid ... This tests new helper function bpf_get_stackid_pe and bpf_get_stack_pe. These two helpers have different implementation for perf_event with PEB entries.
