Android 4.0, it turns out, has a different echo builtin than the other androids.
Until we can figure out how to drop a payload on a 4.0 shell, we cannot support it.
Arch detection allows mips/x86/arm ndkstagers to work, unfortunately
x86 ndkstager was not working, so it is disabled for now.
While @nmonkee didn't actually contribute to #2942, he did publish a
python exploit that leverages WebView, so given our policy of being
loose with author credit, I added him.
Also added a ref to @nmonkee's thing.
@jduck @jvennix-r7 if you have a problem with this, please do say so, I
don't think adding @nmonkee in any way diminishes your work, and I don't
want to appear like we're secretly ripping off people's work. I know you
aren't on this or any other module, and I know @nmonkee doesn't think
that either.
