Subject: [PATCH 3/4] kheaders: rename the 'cpio_dir' variable to 'tmpdir'

The next commit will get rid of the use of 'cpio' command, as there is
no strong reason to use it just for copying files.

Before that, this commit renames the 'cpio_dir' variable to 'tmpdir'.

No functional changes are intended.
