Handle gc-keep-outputs and gc-keep-derivations both enabled
If the options gc-keep-outputs and gc-keep-derivations are both
enabled, you can get a cycle in the liveness graph.  There was a hack
to handle this, but it didn't work with multiple-output derivations,
causing the garbage collector to fail with errors like ‘error: cannot
delete path `...' because it is in use by `...'’.  The garbage
collector now handles strongly connected components in the liveness
graph as a unit and decides whether to delete all or none of the paths
in an SCC.
