This patch added support to print function signature
if btf func_info is available. Note that ksym
now uses function name instead of prog_name as
prog_name has a limit of 16 bytes including
ending '\0'.
The following is a sample output for selftests
test_btf with file test_btf_haskv.o for translated insns
and jited insns respectively.
