Remove the test for absl::base_internal::NominalCPUFrequency() from OSS code

Origin: upstream, https://github.com/abseil/abseil-cpp/commit/732b5580f089101ce4b8cdff55bb6461c59a6720

Remove the test for absl::base_internal::NominalCPUFrequency() from OSS code

This is an internal-only function that should never by called by OSS code.
By its nature fails on unsupported platforms.
Google code has tests for this function on supported internal platforms.

Fixes #1053
