firefox-45, thunderbird-45: support system harfbuzz and graphite2

This commit introduces changes to mozconfig-v6.45.eclass and related changes
to the existing mail-client/thunderbird-45.0 and the new version bump
www-client/firefox-45.1.0 to support using system copies of media-libs/harfbuzz
and media-gfx/graphite2 instead of the copies bundled inside of the mozilla
codebase.

www-client/firefox-45.1.0 was additionally bumped to support security bug 581326

Package-Manager: portage-2.2.26
