TestRunSeccompProfileAllow32Bit: fix

Since the update to Debian Stretch, this test fails. The reason is dynamic
binary, which requires i386 ld.so for loading (and apparently it is no longer
installed by default):

> root@09d4b173c3dc:/go/src/github.com/docker/docker# file exit32-test
> exit32-test: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, BuildID[sha1]=a0d3d6cb59788453b983f65f8dc6ac52920147b6, stripped
> root@09d4b173c3dc:/go/src/github.com/docker/docker# ls -l /lib/ld-linux.so.2
> ls: cannot access '/lib/ld-linux.so.2': No such file or directory

To fix, just add -static.

Interestingly, ldd can'f figure it out.

Other tools (e.g. objdump) also show it's a dynamic binary.

While at it, remove the extra "id" argument (a copy-paste error I
guess).
