sys-boot/lamboot: address review comments

Correct the copyright header (Gentoo Authors + GPL-2), require Python 3.12+
(3.12-3.15), drop the redundant S=, move source preparation into src_prepare,
drop the docs existence check, and stop installing the MIT/Apache-2.0 license
texts (they are already in Gentoo's license tree).
