[Buildroot] [PATCH 1/1] savedefconfig: Remove BR2_DEFCONFIG from saved defconfig file

[Herve Codina]

BR2_DEFCONFIG should not be present in saved defconfig file.

The use case is:
make qemu_arm_versatile
make savedefconfig BR2_DEFCONFIG=my_custom_defconfig

BR2_DEFCONFIG is set in my_custom_defconfig with an absolute path
to qemu_arm_versatile (value present in .config) and set in
my_custom_defconfig as it is different from default mentionned in
config.in (default is BR2_DEFCONFIG from environnement).

On savedefconfig recipe, simply remove BR2_DEFCONFIG from generated file
