Issue Description:
With development snapshot toolchains, swift build/swift run for executable/library targets importing _Differentiation has no problem.
However, running swift test for test targets importing _Differentiation fails with a dynamic linker issue:
$ swift test
[7/7] Linking SwiftDifferentiationPackageTests

Setting DYLD_LIBRARY_PATH to the toolchain library directory containing libswift_Differentiation.dylib does not help:

However, manually invoking the xctest command from swift test -v with DYLD_LIBRARY_PATH does work:

Maybe this is because swift test does not pass the DYLD_LIBRARY_PATH environment variable to the xctest invocation?

That error is present on trunk snapshots, but not on 5.7 branch snapshots. For example, the 2022-05-04 and 2022-06-08 trunk snapshots produce the concurrency error. The 2022-06-04 v5.7 and 2022-06-13 v5.7 snapshots do not. I was building the package using the June 13, 2022 v5.7 Development Snapshot in https://github.com/apple/swift-package-manager/issues/4454#issuecomment-1160881425. Same behavior on the June 8 trunk snapshot though.
Terminal output (before, then after adding platforms to Package.swift)
Most dylibs whose install names are under these directories do not actually exist there as separate files; instead, the dynamic loader picks them up from the system-wide dyld shared cache.
