perf tools: Add missing 'abi' member to 'struct regs_dump'



And store the parsed value there.  Note that the 'abi' is 0 (no
registers), 1 (32-bit registers) or 2 (64-bit registers), but the
registers are anyway copied one-by-one as 64-bit values onto the event
i.e. see 'perf_output_sample_regs()'
