[PATCH v2 5/8] ui-repolist: Factor out logic for emitting a new section heading

For a later commit in this series, this logic is common in a couple
of places.  This simplifies the logic a bit instead of having several
nested checks.  Additionally, this patch removes the need for using
"!strcmp(c->section, "")" as this is equivalent to comparing
"'\0' == repo->section[0]".
