USE flags

• filecaps - Use Linux file capabilities to control privilege rather than set*id (this is orthogonal to USE=caps which uses capabilities at runtime e.g. libcap)
• seccomp - Enable seccomp (secure computing mode) to perform system call filtering at runtime to increase security of programs
• test - Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
