linux-user: sparc64: Use correct target SHMLBA in shmat()

qemu with hax to log dma reads & writes jcs.org/2018/11/12/vfio

In commit 40df8c0c0722 support was added for target-specific
handling of SHMLBA. Unfortunately the sparc64-specific part
of the change got lost somewhere between the patch being
posted to the list and going into master:

Add the accidentally-dropped code.
