sys/resource.h: add rusage compatibility fields, set to zero

Browse Source 
POSIX defines this structure but specifies only two fields (which we
already implement). However, both the *BSD and Linux have agreed on
some more fields, which are often assumed to be there by applications.

The benefice of having compatibility fields is
greater as having to patch every other software at HaikuPorts.
