bitbake.conf/sstate: Introduce OE_SHARED_UMASK to standarise shared area umask

Currently, the "shared" directory permissions of sstate are hardcoded. Since
multiple areas of the code reference this, separate it out to a variable to
allow the behaviour to be configurable. Initially this applies to SSTATE_DIR.
