7228fe68 ("configure: restructure gmime cert validity checker code",
2022-04-09) restructured generated C code to repurpose it later on. This
put usage of `validity` within an `#if`, resulting in an "unused
warning" if that `#if` is not executed.

Put the variable declariation inside the same if branch and, thus,  quel
the warning.

Purely cosmetic. There are more warnings during the build, but this was
the only one during configure, so it stuck out a bit.
