[Support] [Windows] Don't cancel delete if we failed to set delete

Following up on commit 177176f75c, if we
failed to setDeleteDisposition(true) during TempFile creation, then
don't try to setDeleteDisposition(false) during TempFile::keep, since it
will likely fail as well.

Instead of letting TempFile::keep just fail, we should let it go ahead
and try renaming the file.

This fixes an issue we are seeing when running clang-cl.exe through the
Incredibuild distributed build system.  We're seeing that renaming
temporary object files would fail here:
