scripts: trim "__attribute__((packed))" in RPC struct diff

Browse Source 
i686 builds on x86_64 host on Debian 10 result in the RPC structs
getting "__attribute__((packed))" annotations added to them. This is
harmless since we know the XDR protocol aligns and pads struct fields
suitably on the wire. Thus we can safely cull the attribute before doing
the diff comparison.
