[Buildroot] [PATCH 3/8] Revert "avrdude: add license information"

[Ricardo Martincoski <ricardo.martincoski@gmail.com>]

This reverts commit d1f545004bf0533064363d87c2d7c71e7acf7435 from 2014
because the added variables already existed. The real problem at the
time was that one of the pre-existent variables had a typo, fixed in a
later commit.

Currently AVRDUDE_LICENSE and AVRDUDE_LICENSE_FILES are declared twice
with the same values for each one. So remove one of them.

NOTE: When I first sent the series adding check-package, I reported the
typo. Unfortunately I failed to identify the duplicated variables.

The output for below command is the same in current master (f6843a75fe)
and after this patch:
$ make -s BR2_HAVE_DOT_CONFIG=y printvars VARS=AVRDUDE_LICENSE%
AVRDUDE_LICENSE=GPL-2.0+
AVRDUDE_LICENSE_FILES=avrdude/COPYING
