tools/profile: Add additional information to backtrace for -v option

[ekyooo]

Add additional information and change format of backtrace

• add symbol base offset, dso name
• symbol and dso info is included if it's available in target binary
• changed format: ADDR [SYMBOL+OFFSET] (MODULE)

How about change the option name from --verbose to --syms or something else?

verbose is usually used to denote some logs which may useful for developers.
However, the feature in this patch is intended for users, not developers.

[yonghong-song]

In bcc tools, --verbose is mostly used to print out the eventual bpf prog source. In a few instances, the --verbose is used to print out additional information. I think it is good idea to use an option like -a or --address in this case. We can reserve --verbose for future use.

@yonghong-song @Bojun-Seo
What do you think about printing additional information in the backtrace by default, without requiring an option?
Many other tools, such as LeakSanitizer, GDB, and Linux provide extra information by default for enhanced usefulness. You can refer to the backtrace of LeakSanitizer in this GitHub comment.

It seems more reasonable for me to print additional information in the backtrace by default.
