Remove the no_standard_libs property

Corrects an error message that refers to no_standard_libs.

Removes any tests that use no_standard_libs:true where possible as
there are duplicate tests for sdk_version:"none". Otherwise, switches
them over to use sdk_version:"none".

The androidmk mapping from LOCAL_NO_STANDARD_LIBRARIES to
no_standard_libs has also been removed. There was little point in
updating the tool to map it through to sdk_version:"none" as there are
only a couple of places where it is used, in art's test running mk
targets and in some unbundled packages to work around some limitation
in .mk based build.
