Subject: executor: fix endianess of size of received flatbuffers root table

Flatbuffers represents each scalar in little-endian format
(https://flatbuffers.dev/flatbuffers_internals.html). Therefore,
the size of the received root table must be converted to the host endianness
format before its first usage.
