Subject: [PATCH] tests: avoid calling Perl just to determine file sizes

It is a bit ridiculous to spin up a full-blown Perl instance (especially
on Windows, where that means spinning up a full POSIX emulation layer,
AKA the MSYS2 runtime) just to tell how large a given file is.

So let's just use the test-tool to do that job instead.

This command will also be used over the next commits, to allow for
cutting out individual test cases' verbose log from the file generated
via --verbose-log.
