Subject: [PATCH] Disable SysinfoTest.NominalCPUFrequency

SysinfoTest.NominalCPUFrequency in absl_sysinfo_test fails occasionally
on aarch64, but see:

NominalCPUFrequency Test from SysInfoTest Suite Fails on M1 Mac
https://github.com/abseil/abseil-cpp/issues/1053#issuecomment-961432444

in which an upstream author opines:

  If the only problem you are trying to solve is a failing test, this is safe
  to ignore since this code is never called. I should consider stripping this
  test out of the open source release. NominalCPUFrequency is only called in
  code private to Google and we do have tests on the platforms we use it on.

We therefore disable it on all architectures, since any future failures
will also not be meaningful.

Note also that this test is removed upstream in commit
732b5580f089101ce4b8cdff55bb6461c59a6720 (internal commit
7e8da4f14afd25d11713eee6b743ba31605332bf).
