  so adjust required version of databases/rrdtool

Upstream changes:
0.30  (02/21/2010)
    (ms) [RT 53961] Worked around rrdtool-1.3.5 inaccuracy problem by
         skipping certain tests for rrdtool <= 1.4.

0.29  (02/20/2010)
    (ms) Added github repository link to Makefile.PL
    (ms) Fixed documentation for fetch_next().
    (ms) [RT 54544] Tom Regner added support for updatev().

0.28 (11/05/2009)
    (ms) Applied patch by Lyle Brooks, adding optional step, start, and
         end parameters to "draw".

0.27 (10/11/2009)
    (ms) Slaven Rezic reported huge memory consumption by the test suite,
         turned out to be fetch_start() call spanning several years.
         Fixed by defining the end time as well as the start time.

0.26 (09/27/2009)
    (ms) [RT 32601] Using prompt() instead of manually asking for input
         in Makefile.PL (by Fabien Wernli)
    (ms) [RT 32046] Calling setlocale() to fix error message check in
         foreign locales (by Fabien Wernli)
    (ms) Implemented graphv method. This works just like graph() but uses
         rrdtool's graphv internally, giving access to additional
         information using print_results() method (by Fabien Wernli)
    (ms) Improved RRDs version testing (by Fabien Wernli).
