bgpd: Show "(Policy)" under PfxRcd/PfxSnt when eBGP policy is in use

It could be hard to notice when eBGP policy is missing in `show bgp summary`.

This adds more sugar to the output:

Normal:
```
 MsgSent   TblVer  InQ OutQ  Up/Down State/PfxRcd   PfxSnt
      10        0    0    0 00:02:07            6        8
```
When rfc8212 is enabled (default since 7.4) - OUTBOUND:
```
 MsgSent   TblVer  InQ OutQ  Up/Down State/PfxRcd   PfxSnt
      13        0    0    0 00:04:56            6 (Policy)
```
INBOUND:
```
 MsgSent   TblVer  InQ OutQ  Up/Down State/PfxRcd   PfxSnt
      19        0    0    0 00:06:27     (Policy)        2
```
