[Buildroot] [PATCH 1/1] utils/test-pkg: Generate package config if it is not specified

[Vadim Kochan <vadim4j@gmail.com>]

From: Vadim Kochan <vadim4j@gmail.com>

It is possible to generate one-line config for the package just by
normalize it to the form:

    BR2_PACKAGE_${pkg_replaced-to_and_uppercase}

it simplifes a bit of testing package where no additional config options
are needed.
