perf tools: Save cmdline arguments earlier
perf_env__set_cmdline() only saves the arguments the first time it's called. It doesn't need to be called every time the options and suboptions are parsed. Instead it can just be called once. This also has the advantage of making the option parsing code less perf-specific so it can be moved out to a library.
