Allow access to the class jar for java_import using {.jar} tag

Layoutlib requires access to the jar file (containing .class) files for
a number of libraries including "core-libart". It does that using the
{.jar} output tag, e.g. "core-libart{.jar}".

This change makes sure that works when "core-libart" is provided as a
java_import instead of a java_library.
