- Own /usr/lib/tmpfiles.d if not owned by package filesystem

- Update to version 2.7.1
For the first time since version 2.4.0, the database format has
changed slightly, so you will need to run 'mandb --create' after
installing the new version to rebuild your databases from scratch.
- Fixes
* Various portability fixes for Solaris, contributed by Peter Bray.
* man now runs correctly when its current working directory has been
deleted. (As a result of this fix, man-db now requires
libpipeline >= 1.4.0.)
* 'man -a' sends its prompts to /dev/tty rather than to stderr, and
likewise reads replies from /dev/tty rather than from stdin.
* Be more careful to avoid using or double-closing closed database
handles. Fixes test suite failures on some systems.
* Patch the fdutimens function imported from Gnulib to work around a
libc bug in GNU/Hurd.
* Fix test suite in the case where the system supports
high-precision timestamps but the file system containing the build
directory does not.
* lexgrog now filters terminal escape sequences out of cat pages
before trying to parse them.
* Tools that consider the terminal line length now prioritise the
COLUMNS environment variable above the TIOCGWINSZ ioctl.
* Manpath elements are no longer canonicalised before being inserted
into the search path; this caused the use of incorrect catpaths in
some cases. This was broken by the LANGUAGE-handling fixes in
2.5.4.
* Remove test suite dependency on realpath(1).
* Fix a test failure when configured with --enable-undoc.
