perf script: Add option resolving vmlinux path
Add the option get the path of [kernel.kallsyms].
Specify '--show-kernel-path' option to use this function.
This patch enables other applications to use this output easily.
Without --show-kernel-path option

ffffffff81467612 irq_return ([kernel.kallsyms])

With --show-kernel-path option
