[OE-core] [PATCH] sstate: Set umask to 002 before packaging runs

[Phil Blundell]

Otherwise we might end up creating directories under sstate-cache with whatever
random umask has been selected for the task that we're trying to package.  This
would be a bad thing since it might result in losing group write access for
newly created dirs, and/or losing group read access for the sstate files 
themselves.
