package_rpm.bbclass: Set tmppath for rpm to somewhere which won't conflict with the rootfs1.2_M4.rc3.2

If the rootfs has a specific layout in mind for /var/tmp, it should be
free to create this. Preinst scripts trigger rpm to create its tmppath
directory which could potentially conflict with this.

We're seeing issues if the provider of the /var/tmp wants to use a symlink
and a preinst script executes before it has been installed. This change
places tmppath as used by rpm somewhere safe which is already automatically
cleaned up too.
