Subject: [PATCH] Fix getpeereid() compilation on Solaris

The code in getpeereid() is unlikely to compile as ucred_t is an opaque
struct (ucred_t * works but ucred_t does not). Either you need to give
a pointer initialized to NULL and getpeerucred() allocates a new ucred
or you call it with an allocated ucred as in this patch.
