Richard Henderson f0907ff4ca linux-user: Fix waitid return of siginfo_t and rusage 
The copy back to siginfo_t should be conditional only on arg3,
not the specific values that might have been written.
The copy back to rusage was missing entirely.

Ilya LeoshkevichandRichard Henderson fa527b44c2 linux-user: Fix shmat(NULL) for h != g 
In the h != g && shmaddr == NULL && !reserved_va case, target_shmat()
incorrectly mmap()s the initial anonymous range with
MAP_FIXED_NOREPLACE, even though the earlier mmap_find_vma() has
already reserved the respective address range.

Fix by using MAP_FIXED when "mapped", which is set after
mmap_find_vma(), is true.
