add_strerror_r_to_error missing int overload

I am encountering the following error on Alpinelinux (musl-libc based)

```
/tmp/src/intel-graphics-compiler-2.16.0/visa/iga/IGALibrary/system.cpp: In function 'std::string iga::FormatLastError(unsigned int)':

```

https://github.com/intel/intel-graphics-compiler/issues/213 reported the issue first and was fixed in https://github.com/intel/intel-graphics-compiler/commit/d5231d0dbb097ec8a1de070f60ce58afecf2f5bf but github.com/intel/intel-graphics-compiler/commit/f0962ad863a85c4cfc417e57aa046dc73a79e193 actually removed the `int` overload, probably mistaken as unused with glibc based distros.
