UPDATING: reduce noise for non-devel users after 11eda6e334c1

• wlroots* glob matches wlroots-devel which isn't affected
• wlroots* uses non-devel xwayland by default, so not affected
• non-wlroots isn't affected but except arcan and maybe cosmic-comp none builds those outside of poudriere due to dependency bloat
• poudriere ignores UPDATING (binary packages aren't affected)
