[PATCH 1/5] cache.h: remove always unused show_date_human() declaration

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

There has never been a show_date_human() function on the "master"
branch in git.git. This declaration was added in b841d4ff438 (Add
`human` format to test-tool, 2019-01-28).

A look at the ML history reveals that it was leftover cruft from an
earlier version of that commit[1].
