[libc-commits] [libc] [libc] Fix -Wshadow warning in sqrtf128.h (PR #196851)

[Nico Weber via libc-commits]

sqrtf128() contained both `using namespace sqrtf128_internal;` and `using FPBits = fputil::FPBits<float128>;`, but sqrtf128_internal also had a `using FPBits = fputil::FPBits<float128>;`. The outer `using` wasn't actually used, so remove that one.
