[BUG] 用户名为 youqu-user 时 get_process_status 总是返回 False

[peeweep]

使用 self.assert_process_status(True, "dde-control-center") 断言 dde-control-center 进程是否存在时，如果用户名在 GREP_LIST 中，如 youqu-user， get_process_status 无法返回正确的值，只能返回 False。

建议以 uid 的形式显示用户，或者不打印用户名。

$ id
uid=1000(youqu-user) gid=1000(youqu-user) groups=1000(youqu-user),10(wheel) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
