playbooks: bifrost-ironic-install: Fix reboot if iPXE boot failed

Browse Source 
If iPXE boot failed, then make sure the 'reboot' action is really
executed. The problem with 'prompt --timeout...' is that this command
will fail if no key is pressed. However, iPXE exits immediately if
one of the command fails so the 'reboot' action was never executed and
the node was stuck in the following unbootable state.

boot.ipxe : 395 bytes [script]
