Roll src/breakpad/src 027db3c04..9e9c3563a (fix arm64 stack overflow)

This roll pulls a major breakpad fix affecting mainly arm64 (see
crbug.com/534738) and causing a loss of crash reports (mainly on
Android M+)

****** Note for TPMs and stability sheriffs ******
It is possible that the number of Android crashes reported for arm64
will suddenly bump up after this change. This is an expected
consequence of fixing the cause of crash-report loss.
