sanity: TMPDIR ABI change for kernel process

The kernel source is being moved into the sysroot, to do this and
preserve previous builds, we need to change the TMPDIR ABI and
provide a function to uninstall all kernels from the sysroot.

This change adds code to do that and increases the ABI number.
