[Buildroot] [PATCH 3/9] configs/beaglebone: don't use custom post-image script

[unixmania at gmail.com]

From: Carlos Santos <unixmania at gmail.com>

Use support/scripts/genimage.sh, instead, which prevents duplicating
TARGET_DIR under ${BUILD_DIR}/genimage.tmp/root.

Use a post-build script to copy uEnv.txt to BINARIES_DIR, as made for
beagleboneai.

Keep the post-image script because it is still used by beaglebone_qt5.

This should be made for beaglebone_qt5 too, but it's not possible to
test because it' broken since commit a7914499b80r:
