threadmanager.hxx is only included from sw/source/core/docnode

...but itself includes sw/source/core/docnode/cancellablejob.hxx, which only
happens to work because of -I$(dir $(3)) in gb_CObject__command_pattern (in
solenv/gbuild/platform/com_{GCC,MSC}_class.mk).  Clean that up by moving the
file.
