Mimi Zohar 05d659186c evm: prohibit userspace writing 'security.evm' HMAC value 
commit 2fb1c9a4f2 upstream.

Calculating the 'security.evm' HMAC value requires access to the
EVM encrypted key.  Only the kernel should have access to it.  This
patch prevents userspace tools(eg. setfattr, cp --preserve=xattr)
from setting/modifying the 'security.evm' HMAC value directly.
