libbpf-tools/profile: Add module info and symbol offset to backtrace
10fc2be 
Add additional information and change format of backtrace
- add symbol base offset, dso name, dso base offset
- symbol and dso info is included if it's available in target binary
- changed format:
INDEX ADDR [SYMBOL+OFFSET] [(MODULE+OFFSET)]

Print backtrace of ip if it failed to get syms.
