Filter potentially dangerous zig user options

 `--cache-dir` modifies the output cache directory
 `--name` modifies the output name
 `--output(-h)?` modifiers the output generated path/header
 `--verbose-*` emits compiler debug output and is not relevant
 `--mllvm` forwards arguments directly to llvm
