[libc] Update supported riscv libs

[mikhail.ramalho]

Summary

This patch removes some duplicated libs added to entrypoints.txt, adds
new libs supported to entrypoints.txt and updates header.txt

[sivachandra]

I think you need to rebase this.

This actually depends on the setjmp/longjmp patch... I added the dependency here on phabricator, but it seems like the bot doesn't get the parent revisions.

I'll manually restart the check once the setjmp/longjmp patch lands.

At the least, these functions are already enabled: https://github.com/llvm/llvm-project/blob/main/libc/config/linux/riscv64/entrypoints.txt#L456

That is the reason for my comment about rebasing.

[mikhail.ramalho]

Oh, I see. I'll rebase against main then.
