cmake: app: set zephyr_extra_modules from environment
This PR adds the possibility to specify ZEPHYR_EXTRA_MODULES from an environmental variable. To add a custom module mymodule in path/mymodule the variable ZEPHYR_EXTRA_MODULES can be set in `.zephyrrc` as `export ZEPHYR_EXTRA_MODULES=path/mymodule`. Signed-off-by: Laczen JMS <laczenjms@gmail.com>
