    tools: Once again honour, but no longer advertise GIT_HTTP env var
    
    In "build: add autoconf to replace custom checks in tools/check"
    --enable-githttp was introduced.  But we missed this comment where it
    was advertised.
    
    Also, that commit had the effect of uncondtionally setting GIT_HTTP
    from the configure variable.  But the env var has been advertised in
    some places as the way to specify this behaviour, and overriding it is
    just unfriendly.
