Since syscall is outdated and broken for some architectures,
use x/sys/unix instead.
There are still some dependencies on the syscall package that will
remain in syscall for the forseeable future:
Errno
Signal
SysProcAttr
Additionally:
- os still uses syscall, so it needs to be kept for anything
returning *os.ProcessState, such as process.Wait.

The `bufio.Scanner.Scan` method returns false either by reaching the
end of the input or an error. After Scan returns false, the Err method
will return any error that occurred during scanning, except that if it
was io.EOF, Err will return nil.
We should check the error when Scan return false(out of the for loop).

No substantial code change.
Note that some style errors reported by `golint` are not fixed due to possible compatibility issues.

This commit allows additional architectures to be added to Seccomp filters
created by containers. This allows containers to make syscalls using these
architectures. For example, in a container on an AMD64 system, only AMD64
syscalls would be usable unless x86 was added to the filter using this patch,
which would allow both 32-bit and 64-bit syscalls to be used.

This removes the existing, native Go seccomp filter generation and replaces it
with Libseccomp. Libseccomp is a C library which provides architecture
independent generation of Seccomp filters for the Linux kernel.
This adds a dependency on v2.2.1 or above of Libseccomp.
