Subject: [PATCH] qb: Add --datarootdir to configure.

This allows a user to use --datarootdir=PATH to configure the
share directory used for pixmaps, desktop files, man pages and assets.

By default this will be '/usr/local/share'. Assets and man page install
paths can still be configured with:
  --with-man_dir=PATH
and
  --with-assets_dir=PATH

Some operating systems like Haiku use unconventional install paths
and this should allow them to configure their build correctly.
