[oe] [meta-python] python3-multidict build failure

[Craig McQueen]

With python3-multidict v3.3.2, I sometimes get a build error when the build does a make clean:

rm .install-deps
rm: cannot remove '.install-deps': No such file or directory

I reported an issue to the multidict project:
https://github.com/aio-libs/multidict/issues/194

As a work-around, I found a need to define in the recipe (or bbappend):

CLEANBROKEN = "1"
