[Buildroot] [git commit] package/volk: fix licensing information

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=0a397fa6381a4115be22ee9637746bf8c8e1194e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Since 2.5.1, volk has been undergoing a relicensing from GPL-3.0+ to the
LGPL-3.0+, which is still not completely done 5by some large margin), so
it is still covered by the GPL-3.0+, but has parts already covered by
the LGPL-3.0+.

We so far only listed GPL-3.0+, but we also had the license file for the
LGPL-3.0+.

Add LGPL-3.0+ to the list of licenses; the COPYING file is the text of
the GPL-3.0+, so we already had it listed (note: the package has a
COPYING-GPL, but i's a symlink to COPYING).
