qemu: Backport patch to avoid assertion fails on icache line size

Due to a bug in glibc 2.33, the value of the icache line size is now
reported as unsupported option. This breaks qemu at runtime with:

cacheinfo.c:182: init_cache_info: Assertion `(isize & (isize - 1)) == 0'
failed.
Aborted (core dumped)

We haven't caught this one yet because we were already on qemu 5.2.0
when we started to play with glibc 2.33 so it was only reproducible on
dunfell.
