target/ppc: Disable goto_tb with architectural singlestep

Browse source 
The change to use translator_use_goto_tb went too far, as the
CF_SINGLE_STEP flag managed by the translator only handles
gdb single stepping and not the architectural single stepping
modeled in DisasContext.singlestep_enabled.

Fixes: 6e9cc373ec ("target/ppc: Use translator_use_goto_tb")
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1795
