utest 测试pthread_key模块，触发断言

单独创建一个group，进行utest测试，语句pthread_key_setspecific触发断言。
```c
(ptd != NULL) assertion failed at function:pthread_setspecific, line number:52 
```
触发断言位置：

utest代码如下：
test_ut.c
```c
#include <rtthread.h>
#include <unistd.h>

#include "utest.h"

pthread_key_t key = 0;

static void pthread_key_test(void)
{
    int value = 1;
    uassert_int_equal(0, pthread_key_create(&key, NULL));

uassert_int_equal(0, pthread_setspecific(key, &value));

uassert_int_equal(1, *(int*)pthread_getspecific(key));

uassert_int_equal(0, pthread_key_delete(key));
};

static rt_err_t utest_tc_init(void)
{
    return RT_EOK;
}

static rt_err_t utest_tc_cleanup(void)
{
    return RT_EOK;
}

static void testcase(void)
{
    UTEST_UNIT_RUN(pthread_key_test);
}
UTEST_TC_EXPORT(testcase, "components.utilities.utest.sample.key_tc",
                utest_tc_init, utest_tc_cleanup, 10);
```
scons脚本代码如下：
```c
Import('RTT_ROOT')
Import('rtconfig')
from building import *

cwd          = GetCurrentDir()      # 将当前路径赋值给字符串 cwd
src     = Glob('*.c') + Glob('*.cpp')
src     += [cwd + '/zkos/core/osal/test/src/zlibc/rt_ut/test_ut.c']
CPPPATH = [cwd]
group = DefineGroup('zkos', src, depend = [''], CPPPATH = CPPPATH)

Return('group')
```
请问是什么原因？利用pthread_create创建也会触发这个bug
bug2：在utest里直接测试pthread_self()函数也会触发断言
