Brad King ae28ec9f24 ENH: Preserve <pkg>_FIND_XXX vars in find_package ...

When the find_package command loads a module it sets several
<pkg>_FIND_XXX variables to communicate information about the command
invocation to the module.  This restores the original state of the
variables when the command returns.  This behavior is useful when a
find-module recursively calls find_package with NO_MODULE so that the
inner call does not change the values in the find-module.
