smack: Retrieve transmuting information in smack_inode_getsecurity()
commit 3a3d8fce upstream. Enhance smack_inode_getsecurity() to retrieve the value for SMACK64TRANSMUTE from the inode security blob, similarly to SMACK64. This helps to display accurate values in the situation where the security labels come from mount options and not from xattrs.
