Ævar Arnfjörð Bjarmason 0f05f22516 generate-cmdlist.sh: don't call get_categories() from category_list()
This isn't for optimization as the get_categories() is a purely shell
function, but rather for ease of readability, let's just inline these
two lines. We'll be changing this code some more in subsequent commits
to make this worth it.

Rename the get_categories() function to get_category_line(), since
that's what it's doing now.
