    gdb/testsuite: Use default gdb_expect timeout in runto
    
    runto uses a hard-coded timeout of 30s in its invocation of gdb_expect.
    This is normally fine, but for very a slow system (e.g., an emulator) it
    may not be enough time for GDB to reach the intended breakpoint.
    
    gdb_expect can obtain a timeout value from user-configurable variables
    when it's not given one explicitly, so use that mechanism instead since
    the user will have already adjusted the timeout variable to account for
    the slow system.
