explicitly use BPF_FILDROP_CAPTURE when configuring BIOCSFILDROP
BIOCSFILDROP used to just be a flag, ie, any non-zero value was
treated the same, but i'm changing it so different values do different
things. this way the programs should keep working even if i decide
to change the values for these macros.
