os: increase directory reading block size on Unix systems

Browse source 
Reportedly CIFS on RHEL 7 can fail to report files if directories are
read in 4K increments. While this seems to be a CIFS or RHEL bug,
reportedly CIFS does not return more than 5760 bytes in a block, so
reading in 8K increments should hide the problem from users with
minimal cost.

Fixes #24015
