Earlier check whether to include LORA_NODE_CLI in lora_cli.c

[mynewt]

Hi all,

if you want to build a lora node firmware
  pkg.deps:
    - "@apache-mynewt-core/net/lora/node"

without LORA_NODE_CLI support

  syscfg.vals:
        LORA_NODE_CLI: 0
        LORA_NODE_LOG_CLI: 0

and (thus) without shell and parse dependency added to your project, you 
will get an error like:

Compiling repos/apache-mynewt-core/net/lora/node/src/lora_cli.c
Error: repos/apache-mynewt-core/net/lora/node/src/lora_cli.c:23:10: 
fatal error: shell/shell.h: No such file or directory
 #include "shell/shell.h"
          ^~~~~~~~~~~~~~~
compilation terminated.

The attached patch fixes this issue by checking for LORA_NODE_CLI 
support earlier.

Hope I didn't get anything wrong.

Best,
Frank
