Since commit 1f2bfbd00e46 ("kbuild: link of vmlinux moved to a
script"), it is easy to increment .version without using a temporary
file .old_version.

I do not see anybody who creates .tmp_version any more.  Probably
it is a left-over of commit 4e25d8bb9550fb ("[PATCH] kbuild: adjust
.version updating").  Just remove it.
