[Buildroot] [PATCH] legal-info: extract even no-redistribute packages

[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998 at free.fr>

If a package is marked _REDISTRIBUTE = NO, then legal-info will not
try to extract it first.

If that package also declares some _LICENSE_FILES, legal-info fails
if it is the only action we're trying to run:

    $ cat defconfig
    BR2_INIT_NONE=y
    BR2_PACKAGE_LIBFSLCODEC=y
    $ make BR2_DEFCONFIG=$(pwd)/defconfig defconfig
    $ make libfslcodec-legal-info
    /bin/sh: /home/ymorin/dev/buildroot/O/legal-info/licenses.txt: No such file or directory
    make[1]: *** [libfslcodec-legal-info] Error 1

Fix this by always having legal-info extract the archives if one or
more _LICENSE_FILES are specified.
