sys/linux: improve precision of BPF attach targets
How the attach target field is interpreted depends on the program type
[1], which itself depends on the attach type [2] (defined in
attach_type_to_prog_type upstream). This commit encodes the same in
syzkaller to make the attach target field more precise.
Because attach_type_to_prog_type is a simple n to 1 mapping, we can
encode it as defines. We can then use those defines in conditional
fields for the different types of attach targets.
