cache: sync the cache file to disk in the background
This version uses a thread rather than a process, to avoid problems with
waitpid handling. This gives slightly less overall build time reduction than
the separate process for it did (this reduces a -c compile coreutils-native by
about 3 seconds, while the process reduced it by 7 seconds), however this time
is quite insignificant relative to a typical build.
The biggest issue with non-backgrounded syncing is the perceived delay before
work begins, and this resolves that without breaking anything, or so it seems.
