[PATCH] update git-http-backend doc for lighttpd

[Glenn Strauss <gstrauss@gluelogic.com>]

use "GIT_HTTP_EXPORT_ALL" => "1" with a value for best compatiblity.
lighttpd 1.4.51 setenv.add-environment does add vars with empty value.
lighttpd setenv.set-environment does, but was only introduced in 1.4.46

git-http-backend may be found at /usr/libexec/git-core/git-http-backend

scope lighttpd config directives for git-http-backend under "^/git"
