libubootenv: adjust postinstall script and fix inherit usage 

* Replace the hard-coded '/etc' with ${sysconfdir}
* Extend the mmcblk check to prevent updating the environment configuration
  when booting from the EMMC (even though the kernel command line root
  passed is in the form of /dev/mmcblk).
* Switch the conditional inherit to inherit_defer as it depends on
  IMAGE_FEATURES to avoid parse-time ordering issues.
