[PATCH 2/2] [gdb/testsuite] Fix duplicate copyright notices

[Tom de Vries <tdevries@suse.de>]

I found two files in which there were two copyright notices, in both cases
with overlapping year ranges.

Fix this by merging the copyright notices, using a simple startyear-endyear
range, as per this text in gdb/copyright.py:
...
    # We want to use year intervals in the copyright notices, and
    # all years should be collapsed to one single year interval,
    # even if there are "holes" in the list of years found in the
    # original copyright notice (OK'ed by the FSF, case [gnu.org #719834]).
...
