Stop using /bin/ as a source in zconfig.sh

Browse Source 
Test 5, 6, 7, and 7 in zconfig.sh use /bin/ as a source of random
directories and files for their test.  This has lead to unexpected
tests failures because the total size of /bin/ on the test system
isn't checked and it is entirely possible for it to be larger than
the target filesystem.

To resolve this issue we create a somewhat random collection of
files and directories in /var/tmp to use.  On average we expect
about 5MB of data with the worst case being 20MB.  This is large
enough to be interesting and small enough to always fit in the
default test datasets.
