Fix warning: 'XATTR_NAME_SMACK' macro redefined.

Recent Linux uapi <linux/xattr.h> headers define XATTR_NAME_SMACK.
The <sys/xattr.h> include at the top of lib/lsm.h means that even
though the direct include of <linux/xattr.h> is guarded, it may
have already happened transitively anyway.

(The alternative fixes would be to hard-code the correct value for
XATTR_NAME_SMACK here instead, or #undef XATTR_NAME_SMACK.)
