gdbserver/s390: Advertise Z0 packet support.
This is necessary for upcoming tracepoint support - otherwise, setting a tracepoint and a breakpoint on the same address will fail, since gdbserver won't know about gdb's breakpoint. Tested on s390x-ibm-linux-gnu and s390-ibm-linux-gnu, RHEL 7.2. gdb/gdbserver/ChangeLog: * linux-s390-low.c (s390_supports_z_point_type): New function. (struct linux_target_ops): Wire s390_supports_z_point_type in.
