[kvm-unit-tests PATCH] travis.yml: Use TRAVIS_BUILD_DIR to refer to the top directory

[Thomas Huth <thuth@xxxxxxxxxx>]

Travis already has an environment variable that points to the top of
the checked-out source code, TRAVIS_BUILD_DIR. We can use it to avoid
the guessing of the right location of the configure script.
