is_negated_errno: sync MAX_ERRNO with the kernel

Linux kernel used to guarantee that the largest errno value will not
exceed 4095, but SECCOMP_RET_ERRNO support introduced by kernel commit
v3.4-rc2-13-gacf3b2c71ed20c53dc69826683417703c2a88059 inadvertently
broke it.  The guarantee is back with kernel commit
v3.19-8275-g580c57f1076872ebc2427f898b927944ce170f2d.

* syscall.c (is_negated_errno): Set maximum errno value to 4095.
