[PATCH] cirrus.yml: Cover SPICE in the MSYS2 job

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Include the mingw-w64-x86_64-spice package so SPICE is covered:

  C compiler for the host machine: cc -m64 -mcx16 (gcc 12.2.0 "cc (Rev10, Built by MSYS2 project) 12.2.0")
  ...
  Run-time dependency spice-protocol found: YES 0.14.4
  Run-time dependency spice-server found: YES 0.15.1

In particular this would have helped catching the build issue
reported as https://gitlab.com/qemu-project/qemu/-/issues/1553:

  [1851/5253] Compiling C object libcommon.fa.p/ui_spice-core.c.obj
