[Chapel Merge] Increased PMI_MAX_KVS_ENTRIES default value

Merge pull request #18569 from jhh67/T2583

Increased PMI_MAX_KVS_ENTRIES default value.

Previously it was 7 * numLocales which was too few on "tab". 8 worked,
but increased it to 10 to give us a bit of breathing room.

This resolves Cray/chapel-private/#2583.
