Rename config option 'portage_overlay' -> 'repos'

This commit renames the config option 'portage_overlay' to 'repos'.
Also, it renames the method 'portage_overlay' to 'process_repos'
and 'set_portage_overlay' to 'set_repos'. Motivation:

 1) The Gentoo wiki states 'repository' as the preferred term,
    and 'overlay' only as a colloquial
    (https://wiki.gentoo.org/wiki/Ebuild_repository),
    reducing the distinction between the main repository
    and other 'overlay' repositories.

 3) This avoids confusion with filesystem overlays
    (via the config option 'overlay' and 'root_overlay').

 2) The plural form highlights the possibility of specifying
    multiple repositories, continuing 2861038a.
