bpf: add accumulator state to the instruction block hash
This addresses a problem where dissimilar instruction blocks were
improperly hashed to the same value because we were not taking into
account the accumulator state.

Log Message:
-----------
tests: Add 50-sim-hash_collision test
libseccomp utilizes a hash table to manage BPF blocks. It
currently employs MurmurHash3 where the key is the hashed values
of the BPF instruction blocks, the accumulator start, and the
accumulator end. This test was added because of a mishandled
hash collision reported by Tor in GitHub issue #148.
