Use WTF_CPU_UNKNOWN when building for riscv64

Bug: https://bugs.webkit.org/show_bug.cgi?id=271371
Forwarded: no

WebKitGTK doesn't build on riscv64 even with the JIT disabled.
Treating the CPU as unknown is perhaps a bit severe, but it allows us
to get the build done until someone steps up to maintain this
properly.
