[Buildroot] [git commit] imx-codec: add install hooks to fix libraries path

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=3a1f5d1ebaf39c757f64ec083034f50c16288901
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

By default, all the libraries are installed under /usr/lib/imx-mm
which causes problems at runtime.

The hooks are inspired from the mechanism used in the Yocto recipe:
https://github.com/Freescale/meta-fsl-arm/blob/krogoth/recipes-multimedia/imx-codec/imx-codec.inc

Tested with the following commands:
 # gst-launch-0.10 audiotestsrc ! mfw_mp3encoder ! fakesink
 # gst-launch-1.0 audiotestsrc ! imxmp3audioenc ! fakesink

[Peter: drop -mindepth/-maxdepth, add comment explaining why this is done]
