dev-vcs/lazygit: fix LICENSE for dependencies; update format

- I did a typo where I used LICENSES instead of LICENSE when trying to
  append license for go modules. I fixed that
- go-license was generating Gentoo incompatible license names, the issue
  didn't get caught because of the typo. I also fixed that.

See https://bugs.gentoo.org/967017 for more info about the issue related
to go-license

I used my wrapper to fix it, which can be found here:
https://github.com/ingenarel/gentoo-dev-scripts/blob/master/gentoo-go-license

format changes:

- use ${var} instead of $var, which was recommended by negril
- don't use *9999, instead use 9999, it was recommended by negril,
  because packages like blender have versions like 5.0.9999, so using
  a good format logic is nice
