this replaces inefficient pattern of `MIN(TEXTW(..), n)` with drw_fontset_getwidth_clamp() instead, which is far more efficient when we only want up to a certain width. dumping a decently sized (unicode) emoji file into dmenu, I see the startup time drop significantly with this patch. before -> after 360ms -> 160ms this should also noticeably improve input latency (responsiveness) given that calcoffsets() and drawmenu() are pretty hot functions.
