Subject: samhain: rework due to changed cache handling

OE-Core changed the cache handling which made the use of ${BPN} no fail.

| Parsing recipes...WARNING: .../samhain-standalone.bb: Exception during build_dependencies for do_configure
| WARNING: .../samhain-standalone.bb: Error during finalise of .../samhain-standalone.bb
| ERROR: ExpansionError during parsing .../samhain-standalone.bb
| Traceback (most recent call last):
|   File "Var <MODE_NAME>", line 1, in <module>
| bb.data_smart.ExpansionError: Failure expanding variable MODE_NAME, expression was ${@d.getVar('BPN').split('-')[1]} which triggered exception IndexError: list index out of range
| The variable dependency chain for the failure is: MODE_NAME -> SAMHAIN_MODE -> do_configure

Simplify the setting of MODE_NAME and SAMHAIN_MODE by setting them
in the recipe files where we know their values.

bitbake:
ee89ade5 cache/codeparser: Switch to a new BB_CACHEDIR variable for cache location
oe-core:
7c15e03dd3 bitbake.conf: Add BB_HASH_CODEPARSER_VALS
