perf script cs_etm: Add map_pgoff to python dictionary

Extract map_pgoff parameter from the dictionary, and adjust start/end
range passed to objdump based on the value.

A zero start_addr is filtered to prevent output of dso address range
check failures. This script repeatedly sees a zero value passed
in for
      start_addr = cpu_data[str(cpu) + 'addr']

These zero values are not a new problem. The start_addr/stop_addr warning
clutters the instruction trace output, hence this change.
