Allow passing `--platform-id` (`-p`) to build_module_locally.
Currently, the PLATFORM_ID is parsed from the `/etc/os-release`. This
is good default value, but sometimes you want to build module locally
against the different platform stream.
For example building on platform:f29 against the platform:f30 modules. In
that case, we need to be able to override the host PLATFORM_ID and
set it manually chosen value.
