[PATCH 2/4] texlive-common.eclass: support TeX Live 2026 distfiles from d.g.o/pub/proj/tex

Starting with TeX Live 2026, we will use

		 https://distfiles.gentoo.org/pub/proj/tex/

as distfile source. Also add the TEXLIVE_SRC_URI_PROJ_TEX eclass
variable, so that consumers of this eclass can opt-in to using this
distfile location.
