hugepages doc symlinks broken

[Christian Ehrhardt ]

The package hugepages have no own docs but instead symlinks to docs of libhugetlbfs build from the same source package.
This is fine as libhugetlbfs is a dependency, but the links are broken.

Example file from hugetlbfs:
└──╼ ll /usr/share/doc/hugepages/HOWTO.gz
lrwxrwxrwx 1 root root 24 Jan 11 2014 /usr/share/doc/hugepages/HOWTO.gz -> ../libhugetlbfs/HOWTO.gz

Now the file that is there has the lib version in its path:
dpkg -L libhugetlbfs0 | grep HOW
/usr/share/doc/libhugetlbfs0/HOWTO.gz

I checked 2.17-0ubuntu2 (trusty) and 2.19-0ubuntu1 (xenial) which both behave this way.

Should just be packaging and not super critical, but yet worth to report.
