scripts/spdxcheck: Add [sub]directory statistics

Add functionality to display [sub]directory statistics. This is enabled by
adding '-d' to the command line. The optional -D parameter allows to limit
the directory depth. If supplied the subdirectories are accumulated

# scripts/spdxcheck.py -d kernel/
Incomplete directories: SPDX in Files
    ./kernel                         :   111 of   114   97%
    ./kernel/bpf                     :    43 of    45   95%
    ./kernel/bpf/preload             :     4 of     5   80%
    ./kernel/bpf/preload/iterators   :     4 of     5   80%
    ./kernel/cgroup                  :    10 of    13   76%
    ./kernel/configs                 :     0 of     9    0%
    ./kernel/debug                   :     3 of     4   75%
    ./kernel/debug/kdb               :     1 of    11    9%
    ./kernel/locking                 :    29 of    32   90%
    ./kernel/sched                   :    38 of    39   97%

The result can be accumulated by restricting the depth via the new command
line option '-d $DEPTH':
