trap-manager: Remove reqid parameter from install() and change return type

Browse Source 
Reqids for the same traffic selectors are now stable so we don't have to
pass reqids of previously installed CHILD_SAs.  Likewise, we don't need
to know the reqid of the newly installed trap policy as we now uninstall
by name.
