[PATCH v2] build.sh: eliminate potential prompts from mk-build-deps/apt-get

[<Cedric_Hombourger@mentor.com>]

From: Cedric Hombourger <Cedric_Hombourger@mentor.com>

commit 498b128 caused build dependencies to be installed via mk-build-deps.

The tool may ask the user to confirm installation of the dependencies but
would fail when called from bitbake (no stdin). Override the default install
command to add the -y switch to the apt-get command it uses.
