Normalize mtime of Makefile.PL/files with mtime in the future

As EUMM has logic based on the mtime of the Makefile.PL, issues can be encountered when a machine's clock is further in the past than when the Makefile.PL was generated. One way to fix this scenario is to normalize the mtime (with e.g. touch) of Makefile.PL when extracting if it's in "the future". It may or may not be reasonable to do this for all extracted files. There's also the -m option for tar, but that may not work on all tars and I don't think it's a good idea to normalize mtimes of files that will be installed (plus I bet there are tests depending on the mtime of various files).

I believe this logic would fit in the init_tools function of Menlo::CLI::Compat, https://github.com/miyagawa/cpanminus/blob/devel/Menlo-Legacy/lib/Menlo/CLI/Compat.pm#L2745
