ok, implemented the SIP check. (also added SELinux check, which behaves the
same as SIP.)
about the default behavior: `scan-build` command has the other compiler-wrapper
(run compiler & analyzer) and flags can turn this module on. `intercept-build`
default is the library-based and flag can turn the compiler-wrapper
interposition on... i would keep it this way. (and also not make platform
dependent switches into the code.)
