[PATCH v5 08/10] strvec: expose strvec_push_nodup for external use

["Matthew John Cheetham via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Matthew John Cheetham <mjcheetham@xxxxxxxxxxx>

Remove the static modifier from the existing `strvec_push_nodup`
function and define the function is `strvec.h` to make it available for
other callers, making it now possible to append to a `struct strvec`
array without duplication.
