<rdar://43955209> Attempt yet again to make overlong-argv test less flaky.

The last attempted fix relied on the assumption that lit was emulating shell
glob-expansion semantics, which it turns out it does not: lit looks at any 'cd'
command on a RUN line and then applies the specified directory as an absolute
prefix when resolving any subsequent non-absolute globs on the command line.
I.e. it will interpret the second line of:

   RUN: touch /tmp/foo{1,2,3}.swift
   RUN: cd /tmp && echo foo*.swift

as

   RUN: cd /tmp && echo /tmp/foo1.swift /tmp/foo2.swift /tmp/foo3.swift

whereas sh interprets it as (and I wrote the last attempt relying on):

   RUN: cd /tmp && echo foo1.swift foo2.swift foo3.swift

This new attempt therefore bypasses lit entirely and just delegates to sh.
While it might not be the most tasteful choice, it does what we want and in the
process lets us use loops to construct our testcase.
