    scripts/lib/bsp/help.py: Fixed pager for yocto-bsp help
    
    Python3 requires strings to be encoded as bytes before sending them through a subprocess pipe. The 
help.py file is not considering this and fails when issuing paged help commands. This patch adds this 
encoding to solve the problem.
