Drop explicit dependency on core module perl(Exporter)

In the package review, the reviewer noted the explicit dependency on
perl(Exporter), added because of a "use base Exporter" construct in
the code that rpm's automatic dependency finder doesn't find, and asked
if that wasn't a bit redundant given that Exporter is a core module.
The explicit dependency has been removed on the basis that it is
extremely unlikely that perl(Exporter) will ever be split from the main
perl package and hence the explicit dependency is indeed redundant.
