fix: build script should not write outside of OUT_DIR (#939)

See #885

Instead of writing out the result of the parsing of the schema, after
this change the build of the plugins will simply fail.

* plugins/zenoh-plugin-rest/build.rs:
  - don't write out the result of the parsing of the schema in
    zenoh-plugin-rest/config_schema.json5,
  - if the schema does not match the default config.json5, panic.
* plugins/zenoh-plugin-storage-manager/build.rs:
  - don't write out the result of the parsing of the schema in
    zenoh-plugin-storage-manager/config_schema.json5,
  - if the schema does not match the default config.json5, panic.
