libtool: Avoid test failure in OpenBSD

The following errors can be seen for the 'execute mode' test in OpenBSD:
  build/libtool: test: <: missing second argument
  build/libtool: test: >: missing second argument

The cwrapper in OpenBSD cannot parse these symbols as arguments in
execute mode if there are no other characters with them.

* tests/execute-mode.at: Escape '<' and '>' in OpenBSD.
