[PATCH 2/3] var: remove read_var

["Sean Allred via GitGitGadget" <gitgitgadget@gmail.com>]

From: Sean Allred <allred.sean@gmail.com>

With our target git_var value now available, we no longer need to call
into read_var() to find its read() function again. This does avoid a
second loop through git_vars, but mostly it just removes a lot of
duplicated logic.
