qca-nss-ecm: parse and load mod depends

Browse Source 
Since many of ECM's module depends are dynamic and chosen at build time
`kmodloader` seems to have trouble properly loading its dependencies.

Attempt to parse ecm's module depends and load them prior to installing
the module.

This commit also replaces error prone `uci get` command with `config_get`,
in case certain options are missing from `/etc/config/ecm`
