imago killed by io_uring?

Hi,

liburing is Not-For-Us on Alpha since 2022, and if I saw it correctly 
imago was recently twice killed by bfs (which now uses io_uring).

Recent kernels do contain io_uring fixes (e.g. in 5.10.186),
which might or might not be related.

Blacklisting liburing and packages build depending on it on imago might 
be a (not necessarily complete) short-term workaround, currently these 
would be:

Reverse-Build-Depends
=====================
* bfs                           (for liburing-dev)
* ceph                          (for liburing-dev)
* libdex                        (for liburing-dev)
* mariadb                       (for liburing-dev)
* mpd                           (for liburing-dev)
* plocate                       (for liburing-dev)

This is not necessarily a complete workaround since libdex and 
libmariadbd are linked with liburing, but it might be a short-term
workaround.
