IOS/ES: Fix the initial content FD value 

YYCJ is one of the last titles to be completely broken in Dolphin.
It would hang right after the Wii remote screen. Looking at the
game's debug messages reveals that it was failing to find some of
its files.

IOS LLE booted the game just fine, which confirmed that it was an issue
with IOS HLE.

By comparing the ioctlv requests and responses with IOS, it turns out
that one of the very first ES replies was different between IOS HLE and
IOS: there was a mismatch for the content fd returned by ES.

Changing the initial content FD to what IOS returns fixes the issue.

So where did 0x6000000 come from?
