Kostya Kortchinsky 15664fe2c4 [scudo][standalone] Fix for releaseToOS prior to init
Summary:
cferris@ found an issue where calling `releaseToOS` prior to any other
heap operation would lead to a crash, due to the allocator not being
properly initialized (it was discovered via `mallopt`).

The fix is to call `initThreadMaybe` prior to calling `releaseToOS` for
the Primary.

Add a test that crashes prior to fix.
