Mimi Zohar 73b49c736f 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.
