[Buildroot] [RFC 0/4] fix genimage wrapper argument parsing

[Etienne Phelip]

The genimage wrapper can be used in the post-image script but 
BR2_ROOTFS_POST_SCRIPT_ARGS passes BINARIES_DIR as the first argument.

In order to make genimage.sh play nicely with
BR2_ROOTFS_POST_IMAGE_SCRIPT, this patch series shifts the first
argument by one before looping over the other arguments.

When calling genimage.sh directly, one should always pass BINARIES_DIR
as the first argument like:

    ${TOPDIR}/support/scripts/genimage.sh ${BINARIES_DIR} \
        -c path/to/genimage.cfg

Etienne Phelip (4):
  genimage.sh: fix argument parsing
  genimage.sh: fix getopts traces
  genimage.sh: strip getopts EOL characters
  genimage.sh: add usage to die function
