Building selftests in a separate directory like this:

    make O=... -C tools/testing/selftests/bpf

and then running:

    ./test_progs -t btf

causes all the non-flavored btf_dump_test_case_*.c tests to fail,
because these files are not copied to where test_progs expects to find

Fix by removing the flavored build check and using rsync instead of cp:
cp fails because e.g. urandom_read is being copied into itself, and
rsync simply skips such cases. rsync is used by kselftests elsewhere
and therefore is not a new dependency.
