Support the upstream "reopen" mode (broken from the beginning in ports)

When the upstream initscript grew a "reopen" mode with 2.1.17 in late 2013,
our patch stuffed the usage information into the wrong place, so that we
inadvertently disabled the new reopen mode, thus never supported it
through the init script in FreeBSD.

Bump PORTREVISION.
