[PATCH 5/5] insane.bbclass: add package specific skips to sstate hash

[Mikko Rapeli <mikko.rapeli@bmw.de>]

From: Michael Ho <Michael.Ho@bmw.de>

The bbclass currently adds INSANE_SKIP to the sstate hash dependencies
however the package specific skips such as INSANE_SKIP_${PN} are
not added automatically because of how the class references them.

This causes the problem that modifying INSANE_SKIP_${PN} does not
invalidate the sstate cache and can mask build breaking warnings.

Add an anonymous python snippet to explicitly include these additional
relevant skips to the sstate hash.
