Strip debug

[freef4ll]

When using prebuilt swift-syntax with swift package manager, a lot of errors show up like:

warning: (arm64) /Users/runner/work/swift-syntax-xcframeworks/swift-syntax-xcframeworks/derivedData/Build/Intermediates.noindex/swift-syntax.build/debug/SwiftBasicFormat.build/Objects-normal/arm64/BasicFormat.o unable to open object file: No such file or directory

When built by Xcode, this is stripped via SWIFT_SERIALIZE_DEBUGGING_OPTIONS; but stripping the binaries also removes the warning.
