>Description:

Installing a binary package from PKG_PATH=ftp://foo the binary packages
mode as installed does not reflect what was packaged.

>How-To-Repeat:
        1. use a ftp source for PKG_PATH
        2. pkg_add priv (priv chosen since it's a good test case)
        3. notice /usr/pkg/bin/priv is -r-xr-xr-x instead of -r-sr-xr-x
>Fix:
        When package add does the ftp get it doesn't appear to use -p flag
        to tar, so do it!
