[PATCH 2/4] linux-user: Fix shmat() strace

[Ilya Leoshkevich <iii@linux.ibm.com>]

The indices of arguments passed to print_shmat() are all off-by-1,
because arg1 is the ipc() command. Fix them.

New output for linux-shmat-maps test:

    3501769 shmat(4784214,0x0000000000800000,SHM_RND) = 0

Fixes: 9f7c97324c27 ("linux-user: Add strace for shmat")
