Thomas Falcon 26527bd486 perf header: Write bpf_prog (infos|btfs)_cnt to data file 
[ Upstream commit 85c894a80a ]

With commit f0d0f978f3 ("perf header: Don't write empty BPF/BTF
info"), the write_bpf_( prog_info() | btf() ) functions exit without
writing anything if env->bpf_prog.(infos| btfs)_cnt is zero.

process_bpf_( prog_info() | btf() ), however, still expect a "count"
value to exist in the data file. If btf information is empty, for
example, process_bpf_btf will read garbage or some other data as the
number of btf nodes in the data file. As a result, the data file will
not be processed correctly.

Instead, write the count to the data file and exit if it is zero.

Fixes: f0d0f978f3 ("perf header: Don't write empty BPF/BTF info")
