LOG: [scudo][test] Link with -no-pie to be agnostic of CLANG_DEFAULT_PIE_ON_LINUX

This keeps the test behavior unchanged when CLANG_DEFAULT_PIE_ON_LINUX switches
to ON by default.

Note: current clang --target=mips64el-linux-gnu -fpie -pie -fuse-ld=lld
does not link with C++ exceptions, using -pie would lead to

```
ld.lld: error: cannot preempt symbol: DW.ref.__gxx_personality_v0
...
ld.lld: error: relocation R_MIPS_64 cannot be used against local symbol; recompile with -fPIC
...
```
