[rubygems/rubygems] Add mtime to Gem::Package::TarWriter#add_file argument

Since 9e21dd9, Gem::Package::TarWriter#add_file adds the file to
the tar with Gem.source_date_epoch for its mtime.
This behavior breaks the code depending on the previous add_file
behavior.
Therefore, add_file accepts mtime as an argument, and uses
Gem.source_date_epoch if not specified.
