util/cbfstool: Fix GCC error due to a shadowed declaration

There is already a function with the name buffer_size(). Adding a local
variable with the same name will lead to the following error on older
GCC versions (e.g. version 4.4.7):

declaration of 'buffer_size' shadows a global declaration

To fix this rename the local variable to buffer_len.
