rpm: Avoid leaking temporary scriplet files
RPM writes each package scriptlet (post-/preinstall) to
/var/tmp/rpm-tmp.XXXXXX --- a lot of files potentially gets created.
When debugging is enabled, these temporary scriptlet files aren't
cleaned up at all and after a while this results in the filesystem
resources are eaten up (like running out of available inodes).
Normally, the temporary files would have been written to the tmp
directory of the target sysroot (which we can easily clean up), but in
this tree, you can't necessarily run the scriptlets.
