docs: install documentation which is referenced in man pages

Currently the various man pages refer to some other documentation files
in the source tree. For example, xl.cfg.5 refers to
docs/misc/xl-disk-configuration.txt, which in turn refers to
docs/misc/vbd-interface.txt.

Since these files are not packaged, the provided documentation appears
incomplete. Fix this by installing the additional files into DOCDIR and
also adjust the contents of the man pages and affected documentation
files to contain the full path of DOCDIR.

xl.cfg.5 refers to non-existant files named xl-disk-configuration and
xl-network-configuration. Adjust to new DOCDIR location.

Simplify the pod2man call, merge two sed calls into a single one.
