tests/dynports: Include missing string header

aszlig · aszlig · commit 3da0fbc04eaf · 2021-07-09T00:54:14.000+02:00
When compiling on Darwin, we get the following error:

  dynports.cc:94:5: error: no member named 'to_string' in namespace 'std'

The &lt;string&gt; header is not included anywhere in the headers leading to
dynports.cc, so I suspect that on glibc the header is implicitly
included.

Adding an explicit inclusion fixes this and of course is also way more
portable.
