docs: admin-guide: add IGNORE_DIRS example for cscope
The workload tracing guide shows how to build a cscope database by
running cscope command directly. The kernel build system also provides
a cscope target, which supports IGNORE_DIRS for excluding directories
from the generated database.
Mention make cscope and show how to exclude Documentation/ as an example.
