Disable cppcheck, it fails for no good reason :(

See e.g. this run: https://dev.azure.com/pyhandle/hpy/_build/results?buildId=1327&view=logs&j=71490d96-a242-5f1c-bb38-546ccf5abc39&t=31ff8806-cfa1-5f20-3b24-e9367d546093

it fails with:
    nofile:0:0: information: Unmatched suppression: allocaCalled [unmatchedSuppression]

which seems to suggest that --suppress=allocaCalled is not a valid
option. However:

1) it worked until today
2) it works on my machine with the VERY SAME VERSION of cppcheck (1.90)
3) if I remove it, I get a bunch of errors called exactly "allocaCalled"
