gdbstub: Synchronize CPU state unconditionally in gdb_set_cpu_pc
Synchronize the CPU state via cpu_sychronize_state() unconditionally
in gdb_set_cpu_pc() rather than only in some of the target ifdef
ladder cases.
We can divide the CPUs into three categories:
* non-KVM targets: no change of behaviour since we will use the
kvm-stub.c no-op function.
* i386 and s390: no change of behaviour since they were already
calling this function
* PPC (in KVM mode): this fixes an error: failing to synchronise
was accidental and probably a bug.
This also paves the way for other targets (specifically ARM) which
can add KVM support in future without having to add another target
specific change to this bit of code.
