Updating archivers/p5-Archive-Tar from 1.52 to 1.54

Upstream changes:
* important changes in version 1.54 10/09/2009
- Apply a patch from Niko Tyni (ntyni@debian.org) that resolves RT #48879;

    As seen in [rt.cpan.org #48879], although the recommended way of
    retrieving the last error is to use an instance method ($tar->error),
    the returned value is effectively global: an error in one Archive::Tar
    instance changes the error string of another instance.

    This change separates the error strings from each other while keeping
    the (deprecated) global value of $Archive::Tar::error pointing to the
    last error regardless of its instance.

    We also support calling error() as a class method (Archive::Tar->error).
    In this case it returns the global value, which matches the old behaviour.
