ovn-controller-vtep.at: Remove all 'Broken pipe' warning logs from

ovsdb-server.log.

This commit makes the OVN_CONTROLLER_VTEP_STOP remove all 'Broken pipe'
warning logs from ovsdb-server.log before running 'check_log'.  This is in
that *ctl command (e.g. ovn-nbctl) exits right after committing the change
to database;  however, in reaction, some daemon (e.g. ovn-controller-vtep)
may immediately update the database;  this later update may cause database
sending update back to *ctl command if *ctl has not proceeded to exit yet;
and if *ctl command exits before database calling send, the send will fail
with 'Broken pipe' error.
