Fix some licenses substitutions

[orsinium]

Github use some substitutions in license text:

• [year] -- current year.
• [fullname] -- name of repository owner.

Apache 2.0 and ECL 2.0 licenses contains this wrong substitutions: [yyyy] [name of copyright owner]. Many people forget fix it manually. For example, yapf.

I don't know why Travis CI build failed. All fails in "cc-by-4.0", not in edited files.

I'm actualize CC-BY licenses names. Now Travis CI Build is passed

The text in the Apache 2.0 appendix is not intended to be substituted in LICENSE -- only when deployed in file headers. Related info, see #558

The CC names were corrected in SPDX license list 3.1 which was recently released, see spdx/license-list-XML#618 ... thanks for updating so that tests pass. I'll cherry-pick your fix in a new PR.

@mlinksva do you think it would be helpful to include that information in the usage notes / how to apply section for the Apache 2.0 license?

In particular, is it acceptable to omit the appendix from the license file? (That would be the opposite of #558, btw.) I'm asking because PDF.js, one of the example projects using this license, does so in their LICENSE file.

[mlinksva]

@waldyrious yes it is acceptable (and licensee accounts for that by stripping text after "end of terms and conditions"; a test).

I'm ambivalent about adding to the usage notes as I'd rather not cause people to think about modifying the license texts at all, but I could see doing it for Apache 2.0 given the occasional misunderstanding about use of the appendix as a license file. Feel free to make a PR.

Thanks for the clarification. I'll give it a shot.
