kbuild: mergeconfig: move an error check to merge_config.sh
Currently, "make tinyconfig" does not work with "-j" option.
$ make mrproper
$ make -j8 tinyconfig

# configuration written to .config

scripts/kconfig/Makefile:122: *** You need an existing .config
for this target. Stop.
make: *** [tinyconfig] Error 2
As shown above, "allnoconfig" has created the .config file before
mergeconfig is called, but Make still raises a false alarm because
of some sort of race condition.
We can fix this issue by moving the error check to the shell script.
Anyway, scripts/kconfig/merge_config.sh always requires an existing
.config as a base file. It is reasonable to check its existence in
the shell script.
