Fix: add default constructor to TaskRecord for map operator[]

Browse Source 
boost::container::map::operator[] default-constructs the mapped_type
when the key doesn't exist. TaskRecord lacked a default constructor
after the e21b2af refactor (only had an allocator-arg constructor).
Added a static vec_allocator_f (matching RuleStatShm.h pattern) and a
default constructor that initializes data_record with it.
