    Fix signals-state-child.exp in remote testing
    
    Remote testing isn't considered in signals-state-child.exp, so the it
    fails like
    
    shell diff -s /scratch/yao/gdb/build-git/aarch64-linux-gnu/gdb/testsuite/outputs/gdb.base/signals-state-child/standalone.txt /scratch/yao/gdb/build-git/aarch64-linux-gnu/gdb/testsuite/outputs/gdb.base/signals-state-child/gdb.txt^M
    diff: /scratch/yao/gdb/build-git/aarch64-linux-gnu/gdb/testsuite/outputs/gdb.base/signals-state-child/standalone.txt: No such file or directory^M
    (gdb) FAIL: gdb.base/signals-state-child.exp: signals states are identical
    
    This patch is to fix it.
    
    gdb/testsuite:
    
    2016-08-23  Yao Qi  <yao.qi@linaro.org>
    
    	* gdb.base/signals-state-child.exp: Set variables gdb_txt and
    	standalone_txt.  Delete gdb_txt and standalone_txt on host
    	and target.  Spawn the binary on target.  Copy files from
    	target to host.
