Replace sign_uefi.sh with sign_uefi.py

Remove the sign_uefi.sh script and call sign_uefi.py instead. This is in
a separate commit from the one adding the Python script in case we need
to revert.

Test command:
platform/vboot_reference/scripts/image_signing/sign_official_build.sh \
  base build/images/reven/latest/chromiumos_test_image.bin \
  platform/vboot_reference/tests/devkeys \
  build/images/reven/latest/chromiumos_test_image.bin.signed

BRANCH=none
BUG=b:261631233
TEST=Run test command above, verify expected files are signed
