scripts/documentation-file-ref-check: improve tools ref handling
There's a false positive on perf/util:
tools/perf/util/s390-cpumsf.c: Documentation/perf.data-file-format.txt
The file is there at tools/perf/Documentation/, but the logic
with detects relative documentation references inside tools is
not capable of detecting it.
So, improve it.
