linux-user: use target_ulong

Linux syscalls pass pointers or data length or other information of that sort
to the kernel. This is all stuff you don't want to have sign extended.
Otherwise a host 64bit variable parameter with a size parameter will extend
it to a negative number, breaking lseek for example.

Pass syscall arguments as ulong always.
