[Buildroot] [PATCH 1/1] utils/test-pkg: add option to enable NLS support

[Vadim Kochan <vadim4j@gmail.com>]

Sometimes the package or specific configuration should be build with and
without NLS support which requires additionally append NLS related
config options or to have separate config file or use additional shell
script.

So add helper command line option which appends config file with NLS
options to the final config file which is now always stored in temporary
file before merge it with the default configuration (even only -c was
specified).
