Change the way efibootmgr works by specifying bootnum via -b parameter

Browse Source 
Instead of passing the bootnum to each different parameter, require users
to specify -b when running operations that need a bootnum.

This allows activation of a new boot entry at the same time it's created
by adding -a onto the command line.
