linux: make kconfig depend on host-make

Commit 0b9efc991f ("linux: use BR2_MAKE") switched LINUX_MAKE to
$(BR2_MAKE). However, this also implicitly sets LINUX_KCONFIG_MAKE.

Thus, when host-make is being used in a build that has
PER_PACKAGE_DIRECTORIES enabled, the dotconfig step will try to use the
make instance from the host directory, but since it is not listed in
LINUX_KCONFIG_DEPENDENCIES, it won't be available yet at that point in
time.

Add an explicit dependency to LINUX_KCONFIG_DEPENDENCIES to have it
copied over early enough.
