Allow recording ALL_DEPS by setting RECORD_ALL_DEPS

This change enables recording ALL_DEPS information
without having to specify the deps-license goal, which
can be useful to populate the dependencies field of
module-info.json for various types of post-processing.

Usage: `RECORD_ALL_DEPS=true make droid` (preferred), or
`make RECORD_ALL_DEPS=true droid`.

Test: make, inspect module-info.json
Test: RECORD_ALL_DEPS=true make, inspect module-info.json
