Exclude some dynamic pieces from versioning
Stop using MinimumPerl - it is confused by this module

There are several constructs like `local($., $@, $!, $^E, $?)`[1] which
trigger the (imho useless) check in Perl::MinimumVersion[2]

This patch simply stops using the plugin since there is nothing to "fix"
(there is no sane way to make the PPI-based parser understand that $^E and
$! are used in a localization).
Instead declare the minimum version at 5.6, which has been successfully
tested (5.6.1 snd 5.6.2 to be exact)
