the //kernel/linux-4.19 kernel is not the final codes used to
generate linux kernel image, it is patched before compile.
so we should use the patched kernel source to generate uapi
header files.

【背景】
sigaction参数sa_mask的设置方法不符合设置本意，某种情况下会导致进程屏蔽字被覆盖
【修改方案】
修改设置方法，在handle处理前设置屏蔽字，处理后恢复屏蔽字

【影响】
如果用户在handle中设置了屏蔽字，该屏蔽字会在handle结束时会被覆盖掉。已测试了所有
相关用例，均可通过。待在linux验证确认是问题后修复。
