Ninja,Swift: correct response file handling

The response file was being written but not used due to the wrong
variable being configured for Swift.  Swift does compile+link in a
single phase and does not use the `<OBJECTS>` placeholder.  Use the
`<SWIFT_SOURCES>` placeholder instead for the response file substitution
which serves the same purpose.
