swift_library doesn't expand $(GENDIR) #314

I was updating one of my macros to get parity with objc_library, and discovered that $(GENDIR) is silently not expanded in swift_library's copts, whereas objc_library expands it

Anyone who has a use-case for this, please feel free to send a PR with a fix. This can be done with https://docs.bazel.build/versions/4.0.0/skylark/lib/ctx.html#expand_make_variables.
