Subject: [PATCH] Change test utils to use absolute path

In the current implementation, a relative path from the project root is
used to get sample files (e.g., VNF packages) for tests. Due to this,
it's not possible to run a specific test in different place from the
project root.

This patch solves this problem by obtaining absolute paths from a test
file.
