libc.map.txt: remove the two riscv64 special cases.
Yes, sigblock() and sigsetmask() are obsolete, but -- despite being the one responsible for this in the first place -- I'm struggling to justify a pointless difference between riscv64 and arm64/x86-64, given that it's _extra_ work to not have the symbols.
