[oe] [PATCH] Shorten some full paths printed to the user.

[Chris Larson]

Adds a base_path_out convenience function, which prepares a full path for
display to the user.  The initial implementation just makes it relative to
${TOPDIR}.  This function is then used for some messages outputted to the
user (packaged-staging, patch application, clean, unpack tasks).
