ObsoleteFiles.inc: Add libclang_rt libraries for riscv64 for LLVM 14/15.

[jhb]

I upgraded an old riscv64 rootfs that had LLVM 14 and had these old files left around still. LLVM 16 installs the same set, so I assume the same set was present in LLVM 15.

BTW, it seems that none of the powerpc runtime libraries are listed for LLVM 15?

Yeah, these lists are never-endingly out of date :) It's a pity we don't support wildcards in these .inc files...
