Ensure a reasonable umask, and fix up permissions

A fairly global problem was discovered that depending on the build users umask, the directories and files being generated ended up with different permissions. This lead to situations where the first package to be installed setup the permissions and could have lead to bugs and security issues.

This patch set resolves the problem in two ways. First it sets the umask to a sane value for distribution creation, 022. Note: I intentionally left the patches and reverted global umask in this patch set. Without the corresponding changes to bitbake the "Add umask task control" won't do anything.

The package.bbclass change is described within that specific commit. Note there is still one outstanding issue when one package uses a directory and another defines the item in terms of a symlink. I intend to enhance the code to deal with that situation in a future commit.

The following changes since commit f40f936b3ba00e31cae49c22b2633d4deb825533:
