Add convenience functions that wrap FS_IOC_ENABLE_VERITY but take a 'struct libfsverity_merkle_tree_params' instead of 'struct fsverity_enable_arg'. This is useful because it allows libfsverity users to deal with one common struct, and also get the default parameter handling that libfsverity_compute_digest() does.
