CA-399631: Increase the max size of xcp-rrdd-plugins for bug-tool (#6337

)

The size is not enough in xs9, xen-bugtool.log:

> Omitting /dev/shm/metrics/xcp-rrdd-squeezed, size constraint of
xcp-rrdd-plugins exceeded
Omitting /dev/shm/metrics/xcp-rrdd-iostat, size constraint of
xcp-rrdd-plugins exceeded
Omitting /dev/shm/metrics/mem-stats, size constraint of xcp-rrdd-plugins
exceeded
...

- Tested: 4243304 NRPE
Modifying the max_size to 13107200 (1638400 * 8) solved this issue.
1638400 * 2 and 1638400 * 4 are not enough.
