The “ios-like” build flavor is used to build modules that do not exist on macOS for Mac Catalyst. Even though they are built for the “OSX” SDK, they need to have a “MACCATALYST”-style module triple; unfortunately, the transition to naming swiftmodules by module triple in #31170 did not handle this edge case correctly.
This commit handles that by piggybacking on a similar special case used to change the lib/swift subdirectory.
