kgdbts: only use new asm-generic/ptrace.h api when needed

The new instruction_pointer_set helper is defined for people who have
converted to asm-generic/ptrace.h, so don't use it generally unless
the arch needs it (in which case it has been converted).  This should
fix building of kgdb tests for arches not yet converted.
