Ticket 48215 - verify_db.pl doesn't verify DB specified by -a option
Bug Description: verify_db.pl -a only uses the db location for
checking the transaction logs, because it ends up
calling "nsslapd dbverify" which only checks the
db files in the server configuration.
Fix Description: Allow a new argument to be passed to "nsslapd dbverify"
that specifies the db parent directory.
