perf config: Bring perf_default_config to the very beginning at main()
Before this patch each subcommand calls perf_config() by themself,
reading the default configuration together with subcommand specific
options. If a subcommand doesn't have it own options, it needs to call
'perf_config(perf_default_config, NULL)' to ensure .perfconfig is
loaded.
This patch brings perf_config(perf_default_config, NULL) to the very
start of main(), so subcommands don't need to do it.
After this patch, 'llvm.clang-path' works for 'perf trace'.
