    security/nebula: fix build on 32 bit platforms
    
    The structure syscall.Iovec has 32 bit fields on 32 bit platforms,
    64 bit fields on 64 bit platforms.  Go copes poorly with this difference
    (why didn't they just use int?).  Apply a conditional patch to fix the
    build on 32 bit platforms.
    
    Approved by:    portmgr (build fix blanket)

+The syscall.Iovec struct has differently typed fields depending on the
+word size of the architecture.  This patch fixes the build on 32 bit
+platforms but is incorrect on 64 bit platforms.
