sci-libs/cantera: 2.6.0-r2 revision bump

1. EAPI8 bump
2. Add Python 3.11 compat, rm deprecated open U option (upstream patch)
3. Rectrict USE=lapack with >=sci-libs/sundials-6.5.0[lapack?]
4. Set std=c++14 to avoid build fail with upcoming dev-libs/boost-1.82
and sci-libs/sundials-6.5.0 detection (the last is strange).

Bug: https://bugs.gentoo.org/888667
Closes: https://bugs.gentoo.org/888527
Closes: https://bugs.gentoo.org/890427
