Fix directory entry validation.
Bug reported by Miroslav Lichvar and Marek Skalický
* src/bucket.c (gdbm_dir_entry_valid_p): Fix lower limit for
the allowed bucket address. Initial allocation of second block
for the directory can be eventually returned to the available
list when the directory is expanded during bucket splitting.
