ext4/048 will fail when running on older kernels that don't support
the filename wipe feature. The journal checkpoint ioctl is a related
feature, and landed just a little bit after filename wipe feature, so
use support for the journal checkpoint ioctl as a proxy for support
for the filename wipe feature.
Without this change, this test will fail when tesing 5.10, 5.4, and
other LTS kernels.
