[PATCH] remove sysctl net.mpls.maxloop_inkernel

[thomas]

As per https://marc.info/?l=openbsd-misc&m=157191651123338&w=2 this is
no longer used and can be removed.

Before:
$ sysctl -a | grep mpls
net.mpls.ttl=255
net.mpls.maxloop_inkernel=16
net.mpls.mapttl_ip=1
net.mpls.mapttl_ip6=0

After:
$ sysctl -a | grep mpls
net.mpls.ttl=255
net.mpls.mapttl_ip=1
net.mpls.mapttl_ip6=0
