[ovs-dev] [PATCH 2/2] travis: Fail the build if any of the Linux build preparations fail.

[Ben Pfaff]

We want the build to fail if we can't prepare properly for it, but
linux-prepare.sh ignored errors.  This fixes the problem.

This would have made it more obvious where the problem fixed by the
previous commit originated.

(osx-prepare.sh already does the right thing.)
