Patch to suppress event for all-stop mode

I'm debugging a multi-threaded software written in C++ using Eclipse DSF in
all-stop mode. The gdb version is "GNU gdb (GDB) Red Hat Enterprise Linux
7.6.1-51.1.el7".

>From time to time threads are spawned or exited and if gdb detects this while
being suspended, an event "*running,thread-id=all" is received. This makes
Eclipse DSF assume the inferior resumed, although the inferior is still
suspended.

I tracked it down to the function mi_on_resume() in mi-interp.c and developed a
simple patch, that seems to work fine for me at least.
