  1. broker/pmiutil: use larger kvsname buffer 

    Problem: openpmix's libpmi.so PMI_KVS_Get_my_name() fails with
PMI_ERR_INVALID_LENGTH if the kvsname buffer size is less than
its internal PMIX_MAX_NSLEN (255) value, regardless of the size
of the returned string.

Work around this by raising the broker's kvsname buffer size
from 64 to 1024 bytes.

Fixes flux-framework#2746
