[#285] object/eacl: Validate X-headers from the requests, not the responses

Browse source 
In previous implementation of eACL service v2 the response X-headers were
validated at the stage of re-checking eACL. This provoked a mismatch of
records in the eACL table with requests. Fix this behavior by checking the
headers from the request, not the response.
