perf report: Fix alignment of symbol column when -v is given

When -v option is given, the symbol sort key prints its address also but
it wasn't properly aligned since hists__calc_col_len() misses the
additional part.  Also it missed 2 spaces for 0x prefix when printing.

  $ perf report --stdio -v -s sym
