Disable ESLint rule react/sort-comp globally

[willdurand]

The react/sort-comp rule often forces us to either disable it or to write code we did not want to write in the first place (for example, adding attribute declarations in the middle of a class, not at the top of it).

We should disable this rule globally.

@willdurand can this also be ported to eslint-config-amo?

I was hesitant because maybe it was addons-frontend specific, but sure, I will do that!
