u/fuel: Bump & rebase for new deploy arg `-E`
Slight refactor of Armband high states, combine all parts touching
salt minion into a single `armband.salt_minion` state.
Also bring in support for NVRAM-backed domain undefine via
`virt.purge` by passing down the proper flag to libvirt.
While at it, squash mcp/patches touching the same lines of code
in <_modules/seedng.py>, so deploys using `-f` do not fail at the
patch stage (due to conflicting patch lines, checking for `patch -R`
does not work as expected).
