AGS: Fix ReadEncInt32() on big-endian systems

Browse source 
Fixes kq1agdi crashing on big-endian systems, since it tried to allocate
a gigantic amount of memory from MFLUtil::ReadV21() because of the
misread values.

From upstream 5e29a339fc83bf5c06a3a9a3b1c65a2fc4b4e72c
Also includes upstream 427752da015fd93549deef1a31d5e533e5c9319e
