[Buildroot] [PATCH v2 1/2] purge-locales: skip /usr/man and /usr/share/man

[Arnout Vandecappelle (Essensium/Mind)]

These directories are going to be removed anyway, so no point purging
their locales.

This also allows us to simplify the loop a bit.

v2: remove the grep -v man as well, which allows us to use $dir/*
    instead of the funky ls construct.
