lib/oe/sstatesig.py: Exclude common machine specific dependencies from task signatures
Where we have machine specific recipes with well defined behaviour, it makes
no sense to rebuild recipes with these as dependencies whenever the machine
changes. This patch lists those well behaved recipes and excludes them from
the task signatures so we can change MACHINE without invalidating existing
PACKAGE_ARCH binaries.
