ctdb-tests: Factor out setup of fake CTDB_BASE

Several test suites need the CTDB_BASE directory to contain a subset
of the regular contents of that subdirectory.  In some cases there are
symbolic links in the test directory (or a subdirectory) and these
symbolic links need to be fixed at installation time.

Instead, add new function setup_ctdb_base() to set CTDB_BASE, create
the directory and populate it as specified.  This relies on
script_install_paths.sh so it can copy the specified targets.  It also
copies any files from the test directory's etc-ctdb/ subdirectory.
