    bgpd: always display keepalive/hold intervals

    `show bgp neighbors <peer> [json]` was only displaying the configured
    keepalive and holdtime intervals when they differed from the default
    values.  Since default config is still config, let's make sure these
    values are always displayed.

However it mistakenly changed the logic to only display the peer's
timers if the configured value was non-zero.  This updates the logic to
check PEER_FLAG_TIMER to determine if the values were configured,
given 0 is a valid value (to disable keepalives).
