(ITS#6324) slapd -d ? emits incorrect value for LDAP_DEBUG_ANY on x86_64

slapd -d ? emits the incorrect numeric value for LDAP_DEBUG_ANY on x86_64:

$ slapd -d ? Installed log subsystems: Any (18446744073709551615) [...] $ slapd -d 18446744073709551615 unrecognized log level "18446744073709551615"

Debug levels are always treated as type int, which is four bytes on Linux x86_64. loglevel_print() in servers/slapd/bconfig.c seems to blame, since it's using a long-typed format (%lu) instead of an unsigned int-typed one (%u).
