bpf: Test_progs, fix test_get_stack_rawtp_err.c build
The linux-5.4.y commit
8781011a302b ("bpf: Test_progs, add test to catch
retval refine error handling") fails to build when libbpf headers are
not installed, as it tries to include <bpf/bpf_helpers.h>:
progs/test_get_stack_rawtp_err.c:4:10:
fatal error: 'bpf/bpf_helpers.h' file not found
For 5.4-stable (only) the new test prog needs to include "bpf_helpers.h"
instead (like all the rest of progs/*.c do) because 5.4-stable does not
carry commit
e01a75c15969 ("libbpf: Move bpf_{helpers, helper_defs,
endian, tracing}.h into libbpf").
