[collectd] RRDTool slowdowns

[Mirko Buffoni]

Ok, thanks to Alex that confirmed it, rrdtool-1.4 with cairo and pango is 
slower.
So I recompiled collectd 4.10.0 with rrdtool-1.2.30, and now it's zillion 
of times faster than with rrdtool-1.4
I had to specify required libgcrypt-devel during build otherwise I get a 
macro error in configure step.
