NFSD: Add nfsd4_encode_fattr4_acl_trueform_scope
The FATTR4_ACL_TRUEFORM_SCOPE attribute indicates the granularity at
which the ACL model can vary: per file object, per file system, or
uniformly across the entire server.
In Linux, the ACL model is determined by the SB_POSIXACL superblock
flag, which applies uniformly to all files within a file system.
Different exported file systems can have different ACL models, but
individual files cannot differ from their containing file system.
ACL_SCOPE_FILE_SYSTEM accurately reflects this behavior.
