【挑单3.2Release】修复time中TIMEZONE优先使用RTC模块的问题

Browse Source 
方案描述：
1、time中timezone全局变量修改为优先从RTC获取
2、settimeofday接口，linux和posix标准有差异，m核中对齐posix标准,具体如下：
int settimeofday(const struct timeval *tv, const struct timezone *tz)
2.1、linux中：
        tz参数已弃用，一般设置为NULL；
        tv参数，为NULL时返回0，不设置错误码，表示不修改当前时间；
2.2、posix中：
        tv或tz全部为NULL时，返回-1，设置错误码EFAULT；
        tv或tz有一个不为NULL时，不设置相应的参数，返回0；不设置错误码；
3、新增settimeofday接口设置timezone测试用例

BREAKING CHANGE:
修复time中TIMEZONE优先使用RTC模块的问题对外变更描述：
修改int settimeofday(const struct timeval *tv, const struct timezone *tz)接口
settimeofday接口对入参的判断逻辑修改：
1、tv或tz全部为NULL时，返回-1，设置错误码EFAULT；
2、tv或tz有一个不为NULL时，不设置相应的参数，返回0；不设置错误码；
