kconfig: get CONFIG_ prefix from the environment
Currently, the CONFIG_ prefix is hard-coded in the kconfig frontends
executables. This means that two projects that use kconfig with
different prefixes can not share the same kconfig frontends.
Instead of hard-coding the prefix in the frontends, get it from the
environment, and revert back to hard-coded value if not found.
