Mimi Zohar b62d59e574 evm: fix writing <securityfs>/evm overflow 
[ Upstream commit 49219d9b87 ]

EVM_SETUP_COMPLETE is defined as 0x80000000, which is larger than INT_MAX.
The "-fno-strict-overflow" compiler option properly prevents signaling
EVM that the EVM policy setup is complete.  Define and read an unsigned
int.

Fixes: f00d797507 ("EVM: Allow userspace to signal an RSA key has been loaded")
