BUG: Fix config test for target install rules

In single-configuration generators a target installation rule should
apply to all configurations for which the INSTALL command was specified.
The configuration in which the target is built does not matter.

In multi-configuration generators each installation rule must be
associated with a particular build configuration to install the proper
file.  The set of configurations for which rules are generated is the
intersection of the build configurations and those for which the INSTALL
command was specified.
