Current implementation of kselftest-merge only finds config files that
are one level deep using `$(srctree)/tools/testing/selftests/*/config`.
Often, config files are added in nested directories, and do not get
picked up by kselftest-merge.
Use `find` to catch all config files under
`$(srctree)/tools/testing/selftests` instead.

To be more specific here, the binderfs test is not catching the config
entry, so it would be nice to get this into the stable trees as well :)

is find run with $(Q)? It isn't with other instances in the Makefile.

I'm not entirely sure all the ways that $(Q) is used (it looks like it
just gets set to @), but if i run 'KBUILD_VERBOSE=1 make
kselftest-merge' I do see the find command printed before running:
find ./tools/testing/selftests -name config | \
xargs ./scripts/kconfig/merge_config.sh -m ./.config
I noticed find used inconsistently (sometimes with @, sometimes with
$(Q), sometimes with neither), so I picked the usage that seemed most
correct to me.

I agree. Using $(Q) looks correct to me.
