gpt: prepare for tables with n_partition_array_entries != 128

* libparted/labels/gpt.c (gpt_read_PE_array): When computing the size
of the partition array entry, use the value of "number of partition
array entries" read from a GPT header, not the default of 128 that we
use when creating new headers.  Details here:
