news/husky-(hpt|htick): Restore build on FreeBSD 11 and DF
The husky-htp texi file can still be processed by the latest texinfo
programs, so all it needed was USES+= makeinfo to fix FreeBSD 11.
However, the husky-htick texi file is too old, so the makefile was
adjusted to not install info if the base texinfo isn't available.
While here, use PORTDOCS and remove very short pkg-plist file.
The maintainer will be notified so he can restore the info page
on all platforms.
