bgpd: fixed misaligned columns in BGP routes table

Column headers in BGP routes table are not aligned with data when
RPKI status is available.  This was fixed to insert a space at the
beginning of the header and at the beginning of lines that do not
have RPKI status.

This fix requires that several testing templates be adjusted to
match the new output.
