[Libosinfo] [libosinfo 2/2] build: Make sure $(pkgdatadir)/db exists

[Christophe Fergeau]

When creating symlinks to usb.ids/pci.ids, we assume the
destination directory already exists. However, this assumption
could very well break during parallel builds if we try to create
the symlinks before anything create the db/ directory. This commit
creates it explicitly as part of the symlink rule to avoid any
potential issue.
