std: ignore -fmacro-prefix-map flag when parsing NIX_CFLAGS_COMPILE

Since we ignore this flag in `clang_options_data.zig`, it makes sense to ignore it for Nix as well. One thing I've been thinking about is if it would make sense to somehow use `clang_options_data.zig` as source of truth for handling Nix cflags too rather than slap more hard-coded escape hatches.
