Bug 17804: Remove some modules from showdiffmarc.pl

Remove DBI, LibXML, LibXSLT.
Add CGI's -utf8 flag.
Few whitespace changes.

Test plan:
[1] Export an existing record to marcxml.
[2] Edit the file, make some small changes.
[3] Import it again, use a matching rule.
[4] Check the diff on Manage staged. (Here is showdiffmarc.pl)
