[MIR] libextutils-depends-perl, libextutils-pkgconfig-perl (dependency of libcairo-gobject-perl)

not a desktop one, it's a new depends from libglib-perl which is owned by foundations

(or rather it's pulled by foundations and desktop components now so there is no clear owner, any of us can unblock if by filling the MIRs)

(I added libcairo-gobject-perl and a tag so this shows up nicely on the excuses report.)

libextutils-pkgconfig-perl was in main up until precise
libextutils-depends-perl was in main up until trusty

Back then it seems they were in as build-deps that back then needed to be in main still.
Both were a build-dep of libglib-perl for example.

Usually cases that were in main before get a fast path back into main, but one would want to find the old reasoning/discussions in case there were special constraints listed.
Of these two I failed to find the old bugs/mails/... - anyone having old references of these?

Also as of today none of the Teams seems subscribed, so even if we find the old cases and quick-ack the new MIR based on the old discussion, we will need a team to step up and own it from now on.

The Foundations team is happy to subscribe to the bugs about the packages.

Promoted both as trivial perl packages in good standing that don't need further MIR review from the team.
