Tycho Andersen fec7b66905 samples: add an example of seccomp user trap
The idea here is just to give a demonstration of how one could safely use
the SECCOMP_RET_USER_NOTIF feature to do mount policies. This particular
policy is (as noted in the comment) not very interesting, but it serves to
illustrate how one might apply a policy dodging the various TOCTOU issues.

Chad Williamson 8aec836acb samples: seccomp: add .gitignore for untracked executables
git status should be clean following make allmodconfig && make. Add
a .gitignore file to the samples/seccomp directory to ignore binaries
produced there.
