find_package: Search a "system package registry"

Generalize the "user package registry" created by commit ed0650f6 (Teach
find_package to search a "package registry", 2009-09-01).  Define a
corresponding "system" registry key under HKEY_LOCAL_MACHINE.  This
gives package installers a place to create a registry value that points
at the right location for find_package() to locate the package.
