vrf: fix route filtering to preserve IPAM-configured routes

The previous implementation filtered out routes without an explicit
source address (route.Src == nil), which incorrectly removed routes
added by IPAM plugins. IPAM plugins typically configure routes without
setting a source address, causing those routes to be lost when the
interface was moved to the VRF.

The SCOPE_UNIVERSE filter already excludes local and connected routes
that are automatically recreated by the kernel, so the additional
route.Src filter was both unnecessary and harmful.

Fixes #1223
