Avoid "text file busy" in dw2-using-debug-str.expHEADmaster

When I run:

    runtest dw2-using-debug-str.exp

... if I examine the gdb.log, I see:

    objcopy: unable to copy file '[...]/dw2-using-debug-str'; reason: Text file busy

This happens because the inferior is still running, and objcopy --
despite the invocation seemingly not needing this -- tries to open it
for writing.

This patch works around the objcopy oddity by having gdb exit (killing
the inferior) before the invocation.

Fixing this points out that the test does not work in the
--target_board=cc-with-gdb-index case.  This patch also arranges to
issue an "untested" here.
