merge_config.sh: Allow to define config prefix
with CONFIG_ environment variable. merge_config.sh uses CONFIG_ which is used in kernel and other projects. There are some projects which use kconfig with different prefixes (e.g. buildroot: BR2_ prefix). CONFIG_ variable is already used for this purpose in kconfig binary (scripts/kconfig/lkc.h), let's use the same rule for in merge_config.sh.
