cmCommonTargetGenerator: Store working directory for relative paths

The Makefile generators run tools with the current working directory set
to the subdirectory of the build tree for the each target.  The Ninja
generator runs tools with the current working directory set to the top
of the build tree.  Tell cmCommonTargetGenerator where the working
directory will be so it can compute proper relative paths.
