[Apple] Fix `gn gen` when using swift and no_stamp_files

When using swift source files, the outputs cannot be derived from
the sources (due to the "whole module optimisation" model). This
caused `gn gen` to fail an assertion when using no_stamp_files
and whole module optimisation.

Without this change, generating the build for the sample project
(in //examples/ios) would fail like this:

  $ ../../out/gn gen out
  [...:FATAL:ninja_c_binary_target_writer.cc(539)]
  Check failed: swiftmodule->has_dependency_output().

  [...:FATAL:ninja_target_writer.cc(626)]
  Check failed: files.empty().

  [...:FATAL:ninja_c_binary_target_writer.cc(539)]
  Check failed: swiftmodule->has_dependency_output().

Fix this by ensuring HasRealInputs() returns true when the source_set
contains any swift source files.
