Recently I have been building -portable on different platforms and noticed some regressions failures 
(specifically in regress/cmdline/diff.sh). The regression has assumption that the umask is 022 (file perm: 644).
On other platforms, the mask can differ. Setting the umask in common.sh is a simple solution. This i mainly meant for -portable
but doesn't affect any regressions in -main.
