Xymon on Ubuntu 24.04

Sorry to quote myself all the time, but I hope, that I found/fixed the
root cause now.

Seems that there's a bug in the calculation of the buffer size.
The attached patch should fix this.
At least compilation with -D_FORTIFY_SOURCE=3 using this patch no
longer results in buffer overflow messages on my test system.
