Correct Apache-2.0 license
Correct Apache-2.0 license

The canonical text version of the Apache-2.0 license [1], as well as the
version used by GitHub when initializing a new repo, differs from the
copy used by the licensecheck package in three ways, ignoring
whitespace:

1.  The subitems under item 4, "Redistribution", are enumerated using
    lowercase letters.

2.  The terms and conditions end with the phrase "END OF TERMS AND
    CONDITIONS".

3.  The terms and conditions are followed by an appendix, "How to apply
    the Apache License to your work".

This commit updates the local copy to match the canonical one.
