FreeBSD 4 and 5, maybe 3

>Description:

When using NFS, vfs.nfs.access_cache_timeout is set to 2 by /etc/rc.network
Without this sysctl the value would be 60. Since 2 seems to be an
appropriate value, I would suggest to set it in /sys/nfs/nfs.h already.

>How-To-Repeat:

Examine vfs.nfs.access_cache_timeout with and without NFS enabled.

>Fix:
