target: fix copying of licenses for SDK/toolchain

The SDK and target/toolchain copy the license file into their
directories. During the rename/move from LICENSE to a LICENSES
folder, this has not been updated.

Update it now, and include the new COPYING file.

While at it, improve formatting/indent.

Fixes: 882e301461 ("LICENSES: include all used licenses in
LICENSES directory")
