Elliott Hughes 5beddb7d64 Fix pthread_attr_getstack__main_thread.
There were two problems here:

* This would fail when run with unlimited stack, because it didn't know
  that bionic reports unlimited stacks as 8MiB.

* This would leave RLIMIT_STACK small, causing failures to exec (so the
  popen and system tests would fail).

(cherry-pick of 27a9aed81978af792cb06035a1619c8141a5fb5b plus the
new ScopeGuard.h from a3ad450a2e3fb6b3fe359683b247eba20896f646.)
