cmsg: Fix broken tests.

The tests were broken with the introduction of the -O3 compilation
flag, which caused some private bindings to be optimised out, even
though they were used by the tests.  Export the required previously
private bindings.

* gnu/gnunet/util/cmsg.scm: Export cmsghdr:size, align-len and
  cmsghdr.
