tests: Fix wrapper scripts to handle options and tests without breakage

If the -V option is given and no tests are supplied, the "cd" command
in run_tests.sh cause scripts/run_tests to interpret the argument to
-V incorrectly.  Therefore, the wrapper scripts can't use "cd" because
they don't know what the options are doing!

Instead scripts/run_tests searches for each test relative to the
current directory and, if not previously found, then searches relative
to the top-level tests directory.  This is a much better way of doing
things.

Given that run_tests.sh and run_cluster_tests.sh were starting to
contain duplicate complex logic, remove run_cluster_tests.sh and
replace it with a symlink to run_tests.sh.  Run_tests.sh checks $0 to
see what options/defaults to use.  Update INSTALL to deal with this.
