[Buildroot] [PATCH 1/2] board/raspberrypi/post-image.sh: support older defconfigs

[Christopher McCrory <chrismcc@gmail.com>]

Commit ada40afb324 fixed pi3-minuart-bt being changed to miniuart-bt.  Older
defconfig files based on raspberrypi*_defconfigs might have to old call,
BR2_ROOTFS_POST_SCRIPT_ARGS="--add-pi3-miniuart-bt-overlay"
Allow either argument to add the correct miniuart-bt overlay.
