Updating package for p5 module Log::Log4Perl from 1.23 to 1.24

pkgsrc changes:
  - Adjusting license according to module's POD

Upstream changes:
1.24 (2009/07/08)
    *   (ms) Fixed bug with Log::Log4perl::Util::tmpfile_name which
             surfaced on VMS, reported by Ben Humphreys.
    *   (ms) Fixed system-wide threshold to no longer lower appender
             thresholds. Bug reported by Jean-Denis Muys.
    *   (ms) Added benchmark to determine impact of eval-free handlers
    *   (ms) Merged with eval_free branch. Now there are no more
             eval("") statements left in the code, making it much easier
             to debug. Performance on init() is about the same, performance
             on init_and_watch() (noops and logged statements alike) is
             25% slower but still in the range of 400,000/sec on my
             1.80Ghz CPU.
