Use symbolic names not octal constants for file permission flags.

Purely cosmetic patch to make our coding standards more consistent ---
we were doing symbolic some places and octal other places.  This patch
fixes all C-coded uses of mkdir, chmod, and umask.  There might be some
other calls I missed.  Inconsistency noted while researching tablespace
directory permissions issue.
