[PATCH 1/3] Clean up server-kill.exp

[Yao Qi <yao@codesourcery.com>]

This patch is to remove some lines which looks unnecessary.  These
lines were added when server-kill.exp was added.  In the version 1,
https://sourceware.org/ml/gdb-patches/2013-03/msg00691.html the test
calls runto_main and delete breakpoint on main,

+if ![runto_main] {
+    return -1
+}
+
+# Otherwise the breakpoint at 'main' would not cause insert breakpoints during
+# first step.
+delete_breakpoints

However, in the version 2
https://sourceware.org/ml/gdb-patches/2013-03/msg00854.html runto_main
is removed but delete_breakpoints is still there.  AFAICS, the line of
delete_breakpoints can be removed too.
