Normalise licenses to point to valid SPDX ids

Ref. ocaml/opam#3976
This was done semi-manually. I didn't fix invalid licenses, just
normalised the ones that fit.
There are still some pearls like 'GPL-2.1', 'GPL-3 with OCaml linking exception',
or even 'BSD-3-clause with OCaml linking exception' !

Very crude list of sed expressions:
