[缺陷描述]：
[Anolis23.1-GA][Beta][ANCK-6.6.25-2] open_posix_testsuite标准符合度测试，pthread_setschedparam_1-1调用pthread_setschedparam函数返回失败，Error at pthread_setschedparam: rc=1失败，日志如下：

# pwd

# ./pthread_setschedparam_1-1.run-test
Error at pthread_setschedparam: rc=1


github上有相关bug，https://github.com/coreos/bugs/issues/410，通过设置sysctl -w kernel.sched_rt_runtime_us=-1后，该用例执行pass，具体如下：
# cat /proc/sys/kernel/sched_rt_runtime_us
950000

# sysctl -w kernel.sched_rt_runtime_us=-1
kernel.sched_rt_runtime_us = -1

# ./pthread_setschedparam_1-1.run-test
Test PASSED

[重现步骤]：
1、git clone https://github.com/linux-test-project/ltp.git下载社区最新版本ltp
2、cd ltp/testcases/open_posix_testsuite 
3、make all
4、执行相关用例
cd /tmp/tone/run/open_posix_testsuite/conformance/interfaces/pthread_setschedparam;
# ./pthread_setschedparam_1-1.run-test


[期望结果]：
用例执行pass

[实际结果]：
用例执行fail
