Revert seccomp tests that allow it to be used on non-x86 architectures

Unfortunately it turns out that libseccomp 2.2 still does not work
correctly on non-x86 architectures; return to the previous configure
setup of insisting on libseccomp 2.1 or better and i386/x86_64 and
disabling seccomp support in all other situations.

This reverts the two commits:
 * "seccomp: libseccomp version varying according to arch"
   (commit 896848f0d3e2393905845ef2b244bb2601f9df0c)
 * "seccomp: update libseccomp version and remove arch restriction"
   (commit 8e27fc200457e3f2473d0069263774d4ba17bd85)
