perf script: Add the offset field specifier
Add the offset field specifier 'symoff' to show the offset from
the symbols in the output of perf-script. We can get the more
detailed address information.
Output sample:
ffffffff81467612 irq_return+0x0 => 301ec016b0 _start+0x0
ffffffff81467612 irq_return+0x0 => 301ec016b0 _start+0x0
301ec016b3 _start+0x3 => 301ec04b70 _dl_start+0x0
ffffffff81467612 irq_return+0x0 => 301ec04b70 _dl_start+0x0
ffffffff81467612 irq_return+0x0 => 301ec04b96 _dl_start+0x26
ffffffff81467612 irq_return+0x0 => 301ec04b9d _dl_start+0x2d
301ec04beb _dl_start+0x7b => 301ec04c0d _dl_start+0x9d
301ec04c11 _dl_start+0xa1 => 301ec04bf0 _dl_start+0x80
