[gdb/testsuite] Add missing wait in gdb.base/signals-state-child.exp
On OBS I ran into:
...
(gdb) shell diff -s outputs/gdb.base/signals-state-child/standalone.txt \
outputs/gdb.base/signals-state-child/gdb.txt^M
diff: 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
...
I managed to reproduce this by adding "sleep (5)" at the start of main in
signals-state-child.c.
Fix this by waiting on the result of the spawned command.
Tested on x86_64-linux.
