evm: don't copy up 'security.evm' xattr
[ Upstream commit 40ca4ee3136d2d09977d1cab8c0c0e1582c3359d ]
The security.evm HMAC and the original file signatures contain
filesystem specific data. As a result, the HMAC and signature
are not the same on the stacked and backing filesystems.
Don't copy up 'security.evm'.
