Unicode/UCD.t: better handling of errors

This now looks for the PERL_DIFF_TOOL environment variable, and if found
uses that to display some problems.  If not found, it uses is(), with a
message that better output is available through setting this variable.

PERL_DIFF_TOOL is a convention I wasn't familiar with.
