Write adjusted range back to module

Browse source 
In Android, the mmap could be overlapped by /dev/ashmem, we adjusted
the range in https://breakpad.appspot.com/9744002/, but adjusted
range isn't written back to module, this caused the corresponding
module be dropped in BasicCodeModules copy constructor.

This also fix a lot of 'unable to store module' warnings
when dumping Android's minidump.
