tests: fix no vrf1 in bgp_bmp r2

The bgp_bmp test is failing because r2 lacks the vrf1 VRF, which
prevents it from exporting VPN prefixes from the configured vrf1 BGP
instance. Previous versions allowed the export of static BGP prefixes
from a non-existent VRF, so the test passed under those conditions.

Add a vrf1 VRF on r2.
