[PATCH] ARM: i.MX: HAB: Allow for semicolons in HAB environment variables

[Sascha Hauer]

With CONFIG_HAB_CERTS_ENV=y, paths and PKCS#11 URIs to the HAB
certificates are taken from environment variables (allowing for better
integration with build systems). In this case these values are passed
internally via compiler macros (-D) to the imx-image host tool. PKCS#11
URIs usually contain semicolons. The semicolons didn't make it through
to the imx-image configuration file due to wrong escapes. Fix this by
expanding the environment variables using make rather than shell.
