[PATCH 14/14] userns: On alpha modify linux_to_osf_stat to use convert from kuids and kgids

From: Eric W. Biederman

Silencing build errors and potentially allowing people to use osf
system calls in from processes running in a non-default user namespace.

It seems this stat call was missed in my first round of converting the
stat system calls, bother.
