kernel.bbclass, base.bbclass: Fix support for old kernel configuration
This solves a regression introduced by OE-Core:
9b75f6a (kernel:
use oldnoconfig before yes '' | make oldconfig).
The original oe_runmake explicitly calls 'die' command in case of
failure so the fallback code never runs. The fallback code needs
to handle the oe_runmake return code to call the backward
compatible callback so we introduced a new command called
oe_runmake_call which is used by oe_runmake.
This does not change the functional behaviour of oe_runmake so it
avoids any change except for the code which does need to handle
the oe_runmake exit code.
