In glibc versions before 2.33. `libc_nonshared.a` defines `__fxstat/__fxstat64` but there is no `fstat/fstat64`. glibc 2.33 added `fstat/fstat64` and obsoleted `__fxstat/__fxstat64`. Ports added after 2.33 do not provide `__fxstat/__fxstat64`, so our `fstat/fstat64` interceptors using `__fxstat/__fxstat64` interceptors would lead to runtime failures on such ports (LoongArch and certain RISC-V ports). Similar to https://reviews.llvm.org/D118423, refine the conditions that we define fstat{,64} interceptors. `fstat` is supported by musl/*BSD while `fstat64` is glibc only.
