submodule: use strvec_pushf() for --submodule-prefix

Add the option --submodule-prefix and its argument directly using strvec_pushf() instead of via a detour through a strbuf. This is shorter, easier to read and doesn't require any explicit cleanup afterwards. Signed-off-by: René Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
