openvpn: fix ptest

The openvpn 2.7.0 upgrade refactored
tests/unit_tests/openvpn/Makefile.am, changing how test_binaries is
defined. This caused autoreconf to generate Makefiles where
buildtest-TESTS and runtest-TESTS no longer have rule bodies, breaking
the existing ptest recipe which relied on these targets for compilation
and execution. The fix replaces these internal automake targets with
stable interfaces: check-am for compilation and direct binary execution
on target.

+Subject: [PATCH] tests: skip test execution when cross-compiling
+
+The auth-pam unit test Makefile.am unconditionally assigns the TESTS variable,
+causing test execution to fail during cross-compilation because the target
+binaries are not executable on the build host.
