[Buildroot] [git commit] pkg-utils.mk: legal-license-file: handle multiple license files with same name

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=31aa4264d8839d05684e67a238837e8633d1e1bc
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Some packages (kmod, e2fsprogs, ..) contain multiple (different) license
files with the same file name, but in different directories.

These are currently all copied to the same filename in
output/legal-info/licenses/<pkg>, overwriting everything but the last file.

Fix it by recreating the same directory structure under legal-info.
