ldap: Fix substring filter parsing and rendering

The initial (prefix) and final (suffix) strings are specified individually
with a variable number of "any" matches that can occur between these.
The previous implementation assumed a single string and rendered it
as *<string>*.

Reported and PCAP provided by @martinvanhensbergen, thanks!

Closes zeek/spicy-ldap#27
