Automatically check for (unintended) dll dependencies

[jeroen]

A little script that shows dll dependencies in the CI script. This way we can manually inspect if there are any unlisted msys2 dependencies.

I modified the curl PKGBUILD only for testing this script :) We don't have to merge that part.

Is there any way to prevent failing the build script in case there is no dll/exe in the package? Right now all perl package builds fail as ther is no dll or exe in the package:

MSYS2 DLL dependencies:
ldd: missing file arguments
Try `ldd --help' for more information.
[MSYS2 CI] FAILURE: perl-URI: Checking dll depencencies failed.
Command exited with code 1

Ah sorry about that. I'll try to fix that!

OK I sent a PR: #1348

Did you test this? Looks to me it still fails since the function "inherits" the status code of the last command, which is still falsy. Fix in #1379.
