Update p5-Variable-Magic from version 0.42 to version 0.43.

Upstream changes:
0.43    2010-06-25 23:35 UTC
        + Add : The new constant VMG_COMPAT_GLOB_GET tells you whether get magic
                is called for globs. It's true starting perl 5.13.2.
        + Chg : All callbacks are now called within an eval-like context.
                Only free callbacks used to be called that way.
        + Fix : Some exceptions thrown from a free callback could be lost.
        + Fix : Croak messages could sometimes be repeated several times.
        + Fix : t/41-clone.t segfaulting with perl 5.13.2.
