Ticket 49017 - Various minor test failures
    
    Bug Description:
    
    There were a number of tests failing on my system:
    
    * pwdPolicy
    * range_search
    * basic
    
    The source of the issues:
    
    * basis test didn't isolate tests from each other so a test failure with SNMP agent caused other DSE tests to fail
    * range_search was not detecting presence of valgrind previously.
    * range_search was logging an error for NSS that was misformated
    * range_search was not chmodding the correct cert9,key4 and pkcs11 files
    * pwdPolicy was not using the correct paths for sbin
    
    Fix Description:
    
    * Add better isolation to basic test
    * Fix the NSS log format in ssl.c
    * Fix the chmod for the new NSS db format
    * Update the pwdPolicy test to correctly use the sbin paths
