This reverts commit e60ae24052 and fix
non-deterministic failures introduced by the commit.
Fix two issues when attempting to testing parallel scanning using
`swift-scan-test` tools:
* Make sure the BumpPtrAllocator in ScanningService is thread-safe so
there are no race condition when a new slab is allocated.
* Make sure the output of `swift-scan-test` only written from one
thread. This prevents some race conditions when writing to the same
raw_fd_ostream.
