Bug#1018786: numba: autopkgtest needs update for new version of llvmlite: The module `llvmlite.llvmpy` is deprecated

Dear maintainer(s),

With a recent upload of llvmlite the autopkgtest of numba fails in 
testing when that autopkgtest is run with the binary packages of 
llvmlite from unstable. It passes when run with only packages from 
testing. In tabular form:

                        pass            fail
llvmlite               from testing    0.39.0-1
numba                  from testing    0.55.2+dfsg-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 llvmlite to 
testing [1]. Of course, llvmlite shouldn't just break your autopkgtest 
(or even worse, your package), but it seems to me that the change in 
llvmlite was intended and your package needs to update to the new situation.

If this is a real problem in your package (and not only in your 
autopkgtest), the right binary package(s) from llvmlite 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.
