util/cbfstool/lz4frame.c: Add comment to fall through

GCC7 has a new feature called -Wimplicit-fallthrough enabled by
default which checks for fallthrough in switch statements which is a
common error. When a fallthrough is actually intended a comment saying
so will satisfy GCC.

Fixes cbfstool not building with GCC7.
