New port: security/doas

The doas program allows users to run commands as another user (usually
root). The doas program was written by the OpenBSD team to provide a
lightweight, simplified (and more secure) alternative to the sudo command.

Original upstream (OpenBSD) source:
http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/doas/

FreeBSD version: https://github.com/slicer69/doas

NOTE: I added the two patch files to workaround issues mentioned in the PR
about hardcoding of /usr/local.

+This is the FreeBSD port of the OpenBSD "doas" command. The doas program
+allows a regular user to run commands as another user (usually root). The
+doas command is a simplified (hopefully more secure) version of the "sudo"
+command and offers an easier to read/modify configuration.
