[mrtg] integrate rrdcached with mrtg

[JL mrtg]

Hi

I use RRDCACHED_ADDRESS environment variable:
  export  RRDCACHED_ADDRESS=127.0.0.1

I run rrdcached as:
  rrdcached -l 127.0.0.1 <more params>

but when I run mrtg I get:
  ERROR: Cannot update file.rrd with '1257937902:14296586674:19866901102'
The "RRDCACHED_ADDRESS" environment variable is defined, but "dummy" cannot
work with rrdcached. Either unset the environment variable or use "update"
instead

:(
