layout.conf: allow a repository to state the cache is authorative
By authorative, this means "the cache is accurate; skip validation". While
a useful hint for a slight speedup in validation, the true gain is for
repositories that are distributed in a fashion that doesn't preserve mtime;
git primarily. Setting authorative-cache = true results in portage
skipping mtime validation checks for the bundled cache, allowing
for git vcs based repos to distribute a cache.
BUG=chromium-os:21049
TEST=dump a cache into metadata/cache, touch it to now, set layout.conf
to authorative-cache=true, verify it doesn't generate cache entries
for that repo.
