linux-user: Fix TARGET_MTIOCTOP/MTIOCGET/MTIOCPOS values

Browse Source 
The TARGET_MTIOCTOP/TARGET_MTIOCGET/TARGET_MTIOCPOS values
were being defined in terms of host struct types, but
these structures are such that their size might differ
on different hosts. Switch to using a target struct
definition instead.
