app/test-pipeline: fix table hash LRU initialization
app/test-pipeline: fix table hash LRU initialization

macro ‘APP_METADATA_OFFSET’ was not used to initialize
‘signature_offset’ and ‘key_offset’ part of struct
rte_table_hash_lru_params.
Instead integer offset values were directly used.

with this fix 'hash-8-lru', 'hash-16-lru', 'hash-32-lru' table types are
able to forward traffic as expected.
