  [clang][deps] Fix handling of -MT in module command-line

Follow-up to 6626f6fec3d3, this fixes the handling of -MT
* If no targets are provided, we need to invent one since cc1 expects
  the driver to have handled it. The default is to use -o, quoting as
  necessary for a make target.
* Fix the splitting for empty string, which was incorrectly treated as
  {""} instead of {}.
* Add a way to test this behaviour in clang-scan-deps.

  [test] Fix macOS triple check

While the inferred host triple for macOS is something like
<arch>-apple-darwin, it's also valid to have <arch>-apple-macos.
Currently that globally changes whether an SDKROOT is provided in tests,
so make this check more portable.
