392fb29e67 fuzzers|cmake: Disable xml_lpm_fuzzer for -DEXPAT_OSSFUZZ_BUILD=ON 
.. to give OSS-Fuzz a chance at a successful build while their
images are based on Ubuntu 20.04 with too-old Protobuf

2a615bc3c5 xml_lpm_fuzzer: Unstuck MallocHook and ReallocHook 
.. so that they fail single allocations, not all
allocations after a certain point.  Previously
fail_allocations of [6, 2, 20] worked the same way
fail_allocations of [2], likely by accidently.

> Missing variable is:
