duplicated testcase names

["Frank Ch. Eigler" <fche at redhat dot com>]

Hi -

Some of our test cases emit duplicate strings for the dejagnu
pass/fail procedures, which make it harder to identify regressions.
These should be cleaned up to pass subtest names alongside the main
name.

For example on some random rhel6 build,

% egrep 'PASS:|FAIL:' systemtap.sum | sort | uniq -c | awk '$1>1 {print}'

shows 
      2 PASS: compiling labels.c -g
      2 PASS: Invalid Server Client Arguments: -D "foo;bar"
      2 PASS: labels :N .label
      2 PASS: plt
