tools/workqueue/wq_dump.py: fix column alignment in node_nr/max_active section

Browse Source 
On larger machines with many CPUs, max_active values such as 2048
exceed the hardcoded minimum field width of 3 characters, causing the
header and data columns to misalign.

Widen the format specifiers to accommodate 4-digit values and
right-align each nr/max as a single string to keep the output compact.
