Pass the build dir along when running tests

As of 0e1c436, the build directory is
an argument to run_regression_tests.sh. However, the build directory in
falco_tests.yaml is currently hard-coded to /build, with the build
variant influencing the subdirectory.

Clean this up so the entire build directory passed to
run_regression_tests.sh is passed to avocado and used for the build
directory.
