[OE-core] [PATCH 1/2] kernel: redirect merge_config.sh error output to file

[Flavio Suligoi]

In the task:

do_kernel_configme

the errors during execution of the "merge_config.sh" script are
currently lost.
But these errors are very useful for debugging, when there are
problems during the kernel configuration fragments assembly.

This is the reason to save also the error log, in addition to the
existing log.
