homebrew analytics can be disabled in the git config

[kergoth]

Homebrew's message about analytics advises disabling it with git config, i.e. git --git-dir=$(brew --repo)/.git config homebrew.analyticsdisabled true, not via the environment, so it'd be nice if the check for it checked both.

The bug is still current. AFAIK I disabled homebrew analytics through
brew analytics off

Running the check I get
CHECK #13: Homebrew analytics are disabled.... FAILED!

but

% brew analytics
Analytics are disabled.

Homebrew 2.3.0, osx-config-check 7ab816d (cloned)

brew analytics off seems to use the git config

% git --git-dir=$(brew --repo)/.git config homebrew.analyticsdisabled       
true
