Migrate from UInt -> Int

Prior to Swift 4, several XCTest APIs were brought into Swift using the
`UInt` type, in contrast to other Apple system frameworks which consistently
used `Int`. In Swift 4, XCTest began being treated as a system framework
and now uses `Int` as well. This change adapts the swift-corelibs-xctest
API to match.
