[PATCH v2 1/7] git-sh-setup: remove unused git_pager() function

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Remove the git_pager() function last referenced by non-test code in
49eb8d39c78 (Remove contrib/examples/*, 2018-03-25).

We can also remove the test for this added in 995bc22d7f8 (pager: move
pager-specific setup into the build, 2016-08-04), the test that
actually matters is the one added in e54c1f2d253 (pager: set LV=-c
alongside LESS=FRSX, 2014-01-06) just above the removed test.

I.e. we don't care if the "LESS" and "LV" variables are set by
git-sh-setup anymore, no built-in uses them, we do care that pager.c
sets them, which we still test for.
