lineage-sdk res: Set no_framework_libs true

*) Don't depend on framework libs when building our org.lineageos.platform-res
   package (as per framework-res bp).

*) It doesn't work out of the box because our resources refer to android: framework-res
   attributes (and compile fails).

*) We can fix this in soong by making org.lineageos.platform-res depend on
   framework-res (see topic:pie-sdk-no-framework-libs).  This allows us to
   build with no_framework_libs true.
