e2fsprogs: do not symlink tune2fs to findfs

commit c0611b45a998 ("e2fsprogs: symlink e2fsck to fsck.ext{2, 3, 4},
and tune2fs to findfs") introduced a symlink from tune2fs to findfs.

This only works when the included private libblkid library is used, but
commit 5b1660a5387b ("utils/e2fsprogs: Update to 1.43.6") disabled the
usage of this private lib and enabled the shared lib support.

Removing this symlink makes it possible to install tune2fs and findfs
package.
