vtysh: Ignore end when parsing frr.conf

Browse Source 
If we have `end` at the end of the frr.conf, then we never execute
XFRR_end_configuration command, and start/end markers do not work.

This leads to for example waiting BGP configuration parsing thread to hang,
and the peers are in shutdown state until the timer expires.
