Pilight receive match fix for bug 4637 (#4639)

* Pilight: dont protocol as list in COMMAND_SCHEMA

As described in bug #4637 the protocol should not be wrapped in a list
in the spec of COMMAND_SCHEMA because this causes the component to
never successfully match any received rf code.

As pointed ot in PR #4639 the easiest way to do this, is to not derive
COMMAND_SCHEMA from RF_CODE_SCHEMA and specify protocol as simple
string there.

This fixes bug #4637.

* Pilight: Add "unitcode" to command schema.

This adds "unitcode" to the COMMAND_SCHEMA. It is used for example in
the brennenstuhl protocol of pilight.
