[Libomptarget] Add missing explicit moves on llvm::Error

Summary:
Some older compilers, which we still support, have problems handling the
copy elision that allows us to directly move an `Error` to an
`Expected`. This patch adds explicit moves to remove the error. Same as
last patch but I forgot this one.
