[PATCH] parisc: Fix struct ipc64_perm to use userspace-clean types

[Helge Deller]

The current implementation is just wrong. It should not use standard
types like uid_t which may be different if used with 32 or 64bit
userspace. Instead use the __kernel_* types which do not pollute
userspace.

This change fixes build errors like for the trinity debian package.
