And make builtin-trace.c less conditional. Dummy functions will be
called when BUILD_BPF_SKEL=0 is used. This makes the builtin-trace.c
slightly smaller and simpler by removing the skeleton and its helpers.
The conditional guard of trace__init_syscalls_bpf_prog_array_maps() is
changed from the HAVE_BPF_SKEL to HAVE_LIBBPF_SUPPORT as it doesn't
have a skeleton in the code directly. And a dummy function is added so
that it can be called unconditionally. The function will succeed only
if the both conditions are true.
Do not include trace_augment.h from the BPF code and move the definition
of TRACE_AUG_MAX_BUF to the BPF directly.
