package/pkg-utils.mk: move FREESCALE_IMX_EXTRACT_HELPER

This helper was introduced before Freescale was part of NXP. Nowadays,
we have NXP packages, and they do use the same archiving format.

Move the Freescale-specific extract helper to a common location, so
that it can be used by other packages in the future.
