[Android] Define the Android NDK major version for breakpad.

common/android/include/sys/user.h includes some workarounds for specific
NDK versions. Some of those workarounds need to be changed in order to
upgrade the NDK. Defining the NDK major version here will allow breakpad
to use preprocessor guards around the version-specific workarounds, easing
the transition.
