CRASH native_exec combined with early_inject

[derekbruening]

I have not diagnosed the exact cause, but it doesn't seem to be -emulate_brk (which assumes we're in control the whole execution). Given that -native_exec is not high priority, for now I'm just going to change the tests to use late injection.
