This patch provides a workaround for the nasty issue that scp(1) is
found on the server side only if it is in $PATH (due to a ~/.bashrc,
/etc/profile, etc). The default $PATH is out of scope for OpenPKG and is
different across platforms anyway. Nevertheless we want to ensure that
with OpenPKG on the server side, scp(1) is always usable (on the client
side) without having to adjust the system and/or user environment (on
the server side).
