John Ericson 678d1c2aa0 Factor out a LogStore interface
Continue progress on #5729.

Just as I hoped, this uncovered an issue: the daemon protocol is missing
a way to query build logs. This doesn't effect `unix://`, but does
effect `ssh://`. A FIXME is left for this, so we come back to it later.

Eelco Dolstra 3876238546 Add Installable::toDrvPaths()
This is needed to get the path of a derivation that might not exist
(e.g. for 'nix store copy-log').

InstallableStorePath::toDerivedPaths() cannot be used for this because
it calls readDerivation(), so it fails if the store doesn't have the
derivation.
