Disable the bionic hardening patchset to fix boot issues

Browse source 
10+4 devices tested working with bionic hardening patches enabled
but hammerhead and shamu do not boot...

2 of the patches were already found to have issues and disabled
3 other patches were ruled out:
- Stop implicitly marking mappings as mergeable
- Make __stack_chk_guard read-only at runtime
- On 64-bit, zero the leading stack canary byte
Leaves 11+1 patches remaining that need to be tested
But I don't have either of the two known impacted devices.
