[PATCH] perf kallsyms: Fix the usage on the man page

[Sangwon Hong]

First, all man pages highlight only perf and subcommands except perf
kallsyms, which includes the full usage. Fix it for commands to monopolize
underlines.

Second, options can skip when executing perf kallsyms, so add square
brackets between <option>.
