reports: let xml reports catch up with --report and --graph

The text and Dot reports are expected to be identical when generated
directly (--report, --graph) or indirectly (via XML).  The xml
testsuite had not be run for ages, let it catch up a bit.

* src/print-xml.c: Pass the type of the symbols.
* data/xslt/xml2text.xsl
Catch up with the new layout.
Display the symbol types.
Use '•', not '.'
* tests/local.at: Smash '•' to '.' when matching against the direct
text report.
* tests/report.at: Adjust XML expectations.
