btf: guard sublevel>43 against X/lts non-numeric sublevels

fromJSON(inputs.sublevel) threw for the lts tree (sublevel='X', e.g.
5.10.X-android12-lts), failing at template parse time. Short-circuit the
comparison so 'X'/'lts' are handled before fromJSON is evaluated, since those
are modern working lts trees and should keep the fixes.
