base-files: remove strange 2775 perms from dirs like /home

Mark Hatle did the historical research into why this was so,
and found that it originally was via debian import, and then
it morphed over time:

<fray> +#   chown -R root:root ${D}
<fray> +#   cd ${D} && chown root:src     usr/src
<fray> +#   cd ${D} && chown root:staff   var/local
<fray> +#   cd ${D} && chown root:staff   home
<fray> +    cd ${D} && chmod 755  `find . -type d`
<fray> +    cd ${D} && chmod 1777 `cat ${S}/debian/1777-dirs`
<fray> +    cd ${D} && chmod 2775 `cat ${S}/debian/2775-dirs`
<fray> that was the original code
<fray> so THAT is why they're 2775..
<fray> they were original 'src' and 'staff'.. which has gotten lost
      sometime in the last 10 years

<fray> AND the origin:
<fray> commit b45c9ed40bb4f893f99127a21776aef3ae888ad7
<fray> Author: Chris Larson <clarson@kergoth.com>
<fray> Date:   Tue Sep 30 16:30:41 2003 +0000
<fray>     Add base-files 3.0.10 (from debian).
<fray> thats where the brain damage started ... Debian in 2003..

Here we simply convert them to being normal 755 dirs.
