tests: avoid skip due to missing nouser_xattr support

* tests/cp/cp-mv-enotsup-xattr.sh: The nouser_xattr option
is not supported by ext2 since about 2022.  Instead use
ramfs to ensure xattrs are not supported.  We also remove
part of the test that relied on partial xattr support.
Fixes https://github.com/coreutils/coreutils/issues/135
