vfs: restore platform specific POSIX sys_acl_set_file() functions
92b149954237a445594c993b79a860c63113d54b removed SMB_VFS_SYS_ACL_SET_FILE() and
all the VFS module implementations. But sys_acl_set_file() in vfs_default calls
into sys_acl_set_file() in sysacls.c which calls back into platform specific
modules.
