app-doc/kicad-doc: [QA] Various fixes to the ebuild.

vcs-snapshot.eclass is not needed.
Main license is || ( GPL-3+ CC-BY-3.0 ) and some files under GPL-2 only.
Don't change LINGUAS in global scope.
Declare local variables and fix bad assignment in src_configure.

Remove REQUIRED_USE; fall back to a default configuration instead.
Especially global USE_EXPAND variables like LINGUAS or L10N should not
require per-package micro-management of flags.

Package-Manager: portage-2.3.0
