Android: Workaround for ftruncate() issues.

Android: Workaround for ftruncate() issues.

This works around a bug in M that prevents Breakpad from using
ftruncate() in the renderer process.

To do this, skip the calls to ftruncate() when allocating bigger
minidump files and strictly depends on write() to append to the end.

It might be less efficient but this is probably less of an issue on
SD cards. It is much better than not getting crash reports.

TBR. I rewrote the CL description a bit to remove references to we/us/I.

Hmm, the actual commit used my google.com address. Oh well.
