selftests: fib_tests: use per-test return value in subtests

fib_tests mixes use of $ret for both per-test return value and global exit
code. If an earlier subtest fails and a later function sets ret=0, the
script will exit with status 0 even though [FAIL] lines were printed.

Use RET as the per-test return value, as already defined in lib.sh. The
exit code ret will only be set in log_test().
