devel/opengrok: upgrade to 1.13.27
Upgrade to version 1.13.27.
Update pkg-message.
Remove the %%PORTDOCS%% entries from pkg-plist. Setting
PORTDOCS= list-of-files adds them to the plist, and the
redundant entries cause poudriere testport check-plist to
fail.
Add a note about how this style of MASTER_SITES breaks
portscout.
