Fix missing test directory creation.

GCC used in OE-core has "dependency tracking" disabled and
libevent has problem with this.
Due to removed makefile.am/in files in test/sample/include
directories, output directories are not created in
configuration step. Compilation step will fails, when
trying to write to non-existing directory.

Upstream-Status: Inappropriate [Other]
Workaround specific to our build system.
