[src/trunk]: src/usr.bin/make make(1): migrate remaining Lst_Find to Lst_FindB
details: https://anonhg.NetBSD.org/src/rev/3cdc5eef0103

description:
make(1): migrate remaining Lst_Find to Lst_FindB
While here, rename SuffSuffIsSuffix to SuffSuffGetSuffix since a
function named "is" should return a boolean, not a string pointer.
