Update to mes-0.26.1.

Somehow this seems to break kernel bootstrap... Not sure why.

Also tcc riscv64 checksum still needs updating.

Looks like Fiwix hasn't started booting yet when crash happens:

Hmm, downgrading back just tcc to the old version works. So one of those patches...

[stikonas]

For now I've removed tinycc upgrade as it was causing issues with Fiwix. It should be easier to debug if we decouple mes and tinycc upgrade.

This means that riscv64 bootstrap regressed a bit (as new mes removed some special casing for tcc assembly support but we are not using that newer tcc yet), hence I changed target branch to master.

CI is expected to eventually fail due to openssl download URL (see #472).

I've tested both qemu and bwrap modes and it seems to work (qemu is quite slow under Fiwix but I don't think I'm causing that).

Looking good - please update parts.rst and rebase so we can get a clean CI.
