[Buildroot] [PATCH 4 of 5 RFC] busybox: menuconfig: take into account initial settings from config file

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

When busybox-menuconfig is executed from a clean repo, and a custom
configuration file was set, then these custom settings are ignored and
busybox starts from the default configuration.

This patch adds an explicit copy of the custom config file to the menuconfig
target to fix 'make clean busybox-menuconfig'.
