amend copyright & licensing blocks

Current versions of the project files are built upon versions published
and licensed by Daniel Baumann, but are modified copies of those files and
thus need to be marked as such per licensing requirements (afaik he did
not pass along ownership / licensing rights to anyone when he left the
project). We should also be careful to not be misrepresenting such
modified copies as being attributed to Daniel.

Adding a new copyright line referring to "The Debian Live team" should
suffice for this.

The authorship block in man pages has also similarly been updated.

Notes:
 - tweaked a copy of daniel copyright lines stating 2014 instead of 2015.
   both of these cases were in files that i had personally introduced in
   some of my past merged commits that moved some code around. i don't know
   why they stated 2014.
 - binary_onie was introduced in 2018, so that has a 2018 date instead of
   2016 unlike the rest.
 - 'efi-image' is a 3rd-party (Canonical Ltd) work that we bundle, but it
   has been modified by 674794a8f4d61a729d2dbd6d99385d2826138694 and
   36a3ba76347ef72df1c316312ed3a26aa4b0c816 so I similarly added a
   debian live copyright line.
 - 'grub-cpmodules' is similar. it was only changed by the indentation fix
   of 36a3ba76347ef72df1c316312ed3a26aa4b0c816 but modification is
   modification, and this does help cover any possible future changes that
   might be made.
