ref-manual: variables: correct sdk installation default path

The SDKPATH variable seems mistakenly identified as the
default path where the SDK will be installed by the generated
installation script, unless option '-d' or a manual input
overrides this default.

The intended variable is SDKPATHINSTALL. SDKPATH indicates
where the SDK is being composed and built.

The definitions have been added/updated.
