[testsuite] backport semicolon removal to 4.0 (checked in)

[Janis Johnson]

Even thinking about backporting testsuite changes to 4.0-branch has
been painful because of a huge change that removed trailing semicolons.
The solution should have been blindingly obvious: remove trailing
semicolons from .exp files in 4.0 and then deal with the rest.

I made Ben post the whole patch originally, but I'm not doing that
here.  The only changes are removal of tailing semicolons.  Tested on
powerpc64-linux with -m32/-m64, checked in.
