lib/plist.c: fix xbps_array_foreach_cb_multi processing entries multiple times

Browse Source 
the first thread to finish will start again from 0 (`reserved`) until
0+slicecount, next thread will then start from the end of the previous
thread which is already wrong, resulting in processing the first
slicecount*maxthreads entries twice.

The first slicecount*maxthreads entries are accounted by the thread
creation loop and `reserved` has to start at the first unaccounted index.
