execute: needs_{selinux,apparmor,smack} → use_{selinux,apparmor,smack}

These booleans simply store whether selinux/apparmor/smack are supposed
ot be used, and chache the various mac_xyz_use() calls before we
transition into the namespace, hence let's use the same verb for the
variables and the functions: "use"
