cmd: Fix license command
The license command isn't usually built and has a few problems:
- The rules to generate license.h haven't worked in a long time,
re-write these based on the bmp_logo.h rules.
- 'tok' is unused and the license text size has increased
- bin2header.c wasn't grabbing unistd.h to know the prototype for
read().
