libbpf: prefer global symbols as bpf program name source
Libbpf picks the name of the first symbol in the corresponding
elf section to use as a program name. But without taking symbol's
scope into account it may end's up with some local label
as a program name. E.g.:
$ bpftool prog
1: type 15 name LBB0_10 tag 0390a5136ba23f5c
loaded_at Dec 07/17:22 uid 0
xlated 456B not jited memlock 4096B
Fix this by preferring global symbols as program name.
For instance:
$ bpftool prog
1: type 15 name bpf_prog1 tag 0390a5136ba23f5c
loaded_at Dec 07/17:26 uid 0
xlated 456B not jited memlock 4096B
