As previously discussed, add the svn:executable property to all scripts

Remove the requirement for the FreeBSD keyword as it no longer
makes any sense.

Discussed with: dougb, brooks
MFC after: 3 days

Mark scripts as not usable inside a jail by adding keyword 'nojail'.

Some suggestions from: rwatson, Ruben de Groot <mail25@bzerk.org>

o Hook the new files up to the build.
o Make sure all the scripts reference rc.d/netif and not rc.d/network1
