analyse: extend provides map when switching to action input

When switching from a target to the artifacts that are the inputs
of a particular action, the provides map is also switched to provide
additional (besides the inputs) information about the action, in
particular the command. Extend this provides map with the remaining
information, in particular the working directory.
