Revert "Description : adding force option to reboot command."

This reverts commit e03bd8dae27026782e1cf524b78f87637238cf5c.

Description is not enough to keep this, and quite likely the
problem is long gone.

Tizen uses it's own shutdown program (deviced-shutdown) from
around Tizen 5.x, which handles the shutdown sequence exactly
as wanted.

Right now it actually causes more harm than good, as it makes
impossible to run any action for two out of four "shutdown"
actions.
