New port: sysutils/runit-faster

Runit is a daemontools replacement with the following features:

• Service supervision
• Clean process state
• Reliable logging facility
• Fast system bootup and shutdown
• Packaging friendly
• Small code size

This very experimental port comes with a complete suite of
configuration files and services to replace init(8) and rc(8) with
runit for initializing your system. Heavily inspired by Void Linux'
init scripts.

Some fixes applied to sysutils/runit:

• Fix most compiler warnings
• Fix bug where runit will only halt the system instead of powering it off
• Pet rclint for runsvdir
• Pet portlint and regenerate patches
