Replace "base" with "parent"

As per the documentation, parent is encouraged these days: "Unless
you are using the fields pragma, consider this module discouraged
in favor of the lighter-weight parent."

Since we don't use the fields pragma let's use parent. It'll only be
an extra dep for Perl 5.8 users since it's core in 5.10+.
