fstests: remove setup script

fstests: remove setup script

THere is a script that will echo the current setup of the fstests
directory. This is largely the same output as running 'check -n' to
do a dry-run outputs. Hence this script is redundant, not likely to
be widely used and is easily replaced with check itself. Remove it.
