strongswan: fix local_gateway discovery

This has been observed by myself and @luizluca: ip route get is
appending uid0 to the output, as seen from:

root@OpenWrt2:~# ip route get 1.1.1.1
1.1.1.1 via 174.27.160.1 dev eth3 src 174.27.182.184 uid 0
    cache
root@OpenWrt2:~#

so the fix is an anchored match, discarding all else. Also, using
ip -o means never having to do multiline matches...
