Subject: [PATCH v3] scripts/kallsyms.c Make the comment up-to-date with current implementation

The comment in scripts/kallsyms.c describing the usage of
scripts/kallsyms does not reflect the latest implementation.
Fix the comment to be equivalent to what the usage() function prints.

 Changes from V2:
  - tabs in the comment into spaces
  - `scripts/kallsyms` in the comment into `kallsyms`

 Changes from V1:
