The new systemd in 19.09 gives an "Access Denied" error when doing
"systemctl daemon-reexec" on an 19.03 system. The fix is to use the
previous systemctl to signal the daemon to re-exec itself. This
ensures that users don't have to reboot when upgrading from NixOS
19.03 to 19.09.

This commit fixes #26650

The main problem was that the iKVM related libraries are always loaded
from the current working directory. The bundled wrapper script makes
sure to CD to the package root folder. This is a no-go in nix as the
application writes its settings in the current working directory and the
store is read-only.

Workaround: create a directory in the users home, where the required
binaries are symlinked and is writable for the current user.

There was an additional issue that for some BMCs IPMIView relies on
the bundled `stunnel` binary to wrap the iKVM traffic in a TLS tunnel.
Therefore it has to be patched to make it executable and the `killall`
command is needed on the PATH because it is used to terminate the
`stunnel` process upon exit.

The functionality provided by this package has been added to the Idris contrib library (module `Interfaces.Verified`).
Therefore identifiers cannot be disambiguated anymore.
