RPKI SSH key files are globbed and deleted for every VRF before only the current VRF's keys are rewritten, and the file names are not VRF-qualified.

Problem
Glob-unlink runs before VRF selection; key file names are not VRF-qualified.
Impact
Default-VRF RPKI SSH caches lose their keys when a VRF instance commits; same cache name in two VRFs collides.
Suggested fix
Qualify file names with the VRF and delete only that VRF's stale keys.
