print skipped tests and bug report address

This conditionally adds two lines to the summary banner
displayed at the end of `make check'; one is for the count of
skipped tests, and the other is for the bug-report address
(printed on failure).  That's a simple feature I have been
longing for.

Here is a sample output, on three tests (faked to FAIL or SKIP):

PASS: aclocal.test
SKIP: req.test
FAIL: suffix.test
=====================================
1 of 2 tests failed
(1 tests were not run)
Please report to bug-automake@xxxxxxx
=====================================

There is probably room for improvement in both the wording and
the layout; please comment.
