[PATCH 7/9] binman: Fix blank line usage for invalid images warning text

[Jonas Karlman <jonas@kwiboo.se>]

There is no blank line between last missing blob help message and the
header line for optional blob help messages.

  Image 'simple-bin' is missing external blobs and is non-functional: atf-bl31

  /binman/simple-bin/fit/images/@atf-SEQ/atf-bl31:
     See the documentation for your board. You may need to build ARM Trusted
     Firmware and build with BL31=/path/to/bl31.bin
  Image 'simple-bin' is missing external blobs but is still functional: tee-os

  /binman/simple-bin/fit/images/@tee-SEQ/tee-os:
     See the documentation for your board. You may need to build Open Portable
     Trusted Execution Environment (OP-TEE) with TEE=/path/to/tee.bin

  Some images are invalid

With this a blank line is inserted to make the text more readable.
