copy: handle ENOTSUP from copy_file_range()

* src/copy.c (sparse_copy): Ensure we fall back to
a standard copy if copy_file_range() returns ENOTSUP.
This generally is best checked when checking ENOSYS,
but it also seems to be a practical concern on Centos 7,
as a quick search gave https://bugzilla.redhat.com/1840284
