chore: use pillow 12.1.1 for python >= 3.10

- fix for vulnerability (OOB write) https://github.com/trezor/trezor-firmware/security/dependabot/109
- pillow is used only by `toiftool`(python CLI tool), the issue does not affect the firmware itself
- patched pillow version (12.1.1) is not compatible with python 3.9, fix affects only usage with python >= 3.10
