perf tools: Remove unused 'prefix' from builtin functions
We got it from the git sources but never used it for anything, with the
place where this would be somehow used remaining:
static int run_builtin(struct cmd_struct *p, int argc, const char **argv)
{
prefix = NULL;
if (p->option & RUN_SETUP)
prefix = NULL; /* setup_perf_directory(); */
Ditch it.
