kbuild: modpost: include .*.cmd files only when targets exist
commit 944cfe9be1fbbec73bab2f7e77fe2e8f9c72970f upstream.
If a build rule fails, the .DELETE_ON_ERROR special target removes the
target, but does nothing for the .*.cmd file, which might be corrupted.
So, .*.cmd files should be included only when the corresponding targets
exist.
Commit 392885ee82d3 ("kbuild: let fixdep directly write to .*.cmd
files") missed to fix up this file.
