Richard Henderson a4ad4a9d98 linux-user: Handle short reads in mmap_h_gt_g

In particular, if an image has a large bss, we can hit
EOF before reading all host_len bytes of the mapping.

Create a helper, mmap_pread to handle the job for both
the larger block in mmap_h_gt_g itself, as well as the
smaller block in mmap_frag.
