[PATCH] gdb/testsuite: fix an issue that prevents selftest

[Enze Li <enze.li@hotmail.com>]

When running gdb.gdb/selftest.exp, I see the following warning,
...
(gdb) break captured_main
Breakpoint 1 at 0x4fdab2
(gdb) run -nw -nx -iex "set height 0" -iex "set width 0"
Starting program: /home/lee/dev/binutils-gdb/gdb/testsuite/outputs/gdb.gdb/selftest/xgdb -nw -nx -iex "set height 0" -iex "set width 0"
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Breakpoint 1, 0x0000555555a51ab2 in captured_main(void*) ()
(gdb) FAIL: gdb.gdb/selftest.exp: run until breakpoint at captured_main
WARNING: Couldn't test self
testcase /home/lee/dev/binutils-gdb/gdb/testsuite/gdb.gdb/selftest.exp completed in 1 seconds
...

Work around this by adding a dot and an asterisk in pattern instead of a
space.

Tested on x86_64-linux.
