exec_cmd.c: use find_last_dir_sep() for code simplification

We are trying to extract dirname from argv0 in the git_extract_argv0_path(). But in the same time, the <git-compat-util.h> provides find_last_dir_sep() to get dirname from a given path. Let's use it instead of loop for the code simplification. Signed-off-by: Alexander Kuleshov <kuleshovmail@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
