cobol: Don't display 0xFF HIGH-VALUE characters in testcases. [PR120251]

The tests were displaying 0xFF characters, and the resulting generated
output changed with the system locale.  The check_88 test was modified
so that the regex comparisons ignore those character positions. Two
of the other tests were changed to output hexadecimal rather than
character strings.

There is one new test, and the other inspect testcases were edited to
remove an unimportant back-apostrophe that had found its way into the
source code sequence number area.
