webpki-roots/webpki-root-certs: prepare 0.26.6, fix license data

[cpu]

These crates mistakenly had license files included for Apache and MIT licenses. Both are derived works under an MPL 2.0 license

Resolves #79

Proposed release notes

• Corrects the license file distributed with the webpki-roots and webpki-root-certs crates to properly reflect the MPL 2.0 license.

@djc @ctz I'm leaning towards yanking 0.26.4 and 0.26.5 once this 0.26.6 release is published. WDYT? (Edit: convinced this is unnecessary)

[ctz]

I don't see the need to yank the old versions -- this is merely an administrative error and doesn't change the actual license they were released under.

this is merely an administrative error and doesn't change the actual license they were released under.

That's fair, I buy the argument that the Cargo.toml license field is more authoritative than the included license files and was set correctly:

webpki-roots/webpki-roots/Cargo.toml

Line 6 in a533475

license = "MPL-2.0"

webpki-roots/webpki-root-certs/Cargo.toml

Line 6 in a533475

license = "MPL-2.0"

Sorry, forgot to add proposed release notes. Just added.

I'll wait a little bit in case anyone feels I've missed the mark on those and then complete the release.
