Philippe Mathieu-Daudé ef0cf1887e tests/qtest/fdc-test: Add a regression test for CVE-2021-20196 
Without the previous commit, when running 'make check-qtest-i386'
with QEMU configured with '--enable-sanitizers' we get:

  AddressSanitizer:DEADLYSIGNAL
  =================================================================
  ==287878==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000344
  ==287878==The signal is caused by a WRITE memory access.

Add the reproducer for CVE-2021-20196.
