Bug#1085288: libtest2-plugin-uuid-perl: autopkgtest needs update for new version of perl

Dear maintainer(s),

With a recent upload of perl the autopkgtest of
libtest2-plugin-uuid-perl fails in testing when that autopkgtest is run
with the binary packages of perl from unstable. It passes when run with
only packages from testing. In tabular form:

pass fail
perl from testing 5.40.0-6
libtest2-plugin-uuid-perl from testing 0.002009-1
all others from testing from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of perl to testing
[1]. Of course, perl shouldn't just break your autopkgtest (or even
worse, your package), but it seems to me that the change in perl was
intended and your package needs to update to the new situation. This
appears to me the test fails on a new warning.

If this is a real problem in your package (and not only in your
autopkgtest), the right binary package(s) from perl should really add a
versioned Breaks on the unfixed version of (one of your) package(s).
Note: the Breaks is nice even if the issue is only in the autopkgtest as
it helps the migration software to figure out the right versions to
combine in the tests.

Bug #1085288 [src:libtest2-plugin-uuid-perl] libtest2-plugin-uuid-perl: autopkgtest needs update for new version of perl
Added indication that 1085288 affects src:perl

[gregor herrmann]

So I guess this needs either
- some friendly hint for the autopkgtest system
- or we can add the TEST2_UUID_NO_WARN env variable, which I didn't
know about before this bug report
I'm happy to do the latter, as it seems fair in general.

Except that we can only set environment variables for the "smoke"
test but not for the failing "use.t" test.

*sigh*

So either some intervention in the autopkgtest system is needed, or
we drop all arch:all packages from Depends or something like that :/

Cheers,
gregor
