GUACAMOLE-1259: Include missing config.h header for sake of conditional Stream_Free().
The changes introduced by GUACAMOLE-1181 (commit 2c86e20) were made
conditional as older versions of FreeRDP will automatically free the
wStream, resulting in a double-free if we attempt to do so ourselves.
The macro controlling that conditional code is defined within config.h,
which is missing here. Without that macro, the call to Stream_Free()
always occurs, and we get a double-free with older FreeRDP.
