Fix cc_shared_library error with hdr-only libraries
cc_libraries with a linker_input with no libraries (either because they contain only headers or only linkopts) caused errors in cc_shared_libraries triggered by a check that made sure that a cc_library wasn't linked more than once into different shared libraries. That check can be ignored in those cases.
