[U-Boot] [PATCH] .travis.yml: explicitly request sudo

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

Without this, builds default to using new Travis CI infra-structure which
does no allow sudo. The builds need sudo in order to install the ELDK
compilers. Consequently, almost all builds fail without this.

I suspect that existing Travis CI users have not noticed this because
their accounts or builds have been grand-fathered into backwards-
compatible default settings, whereas I just set up a new build from
scratch and received new default settings.
