build/boot/*: unified main() function

The *same* main() function is now used on both scripts.

However, merging both scripts together would be less efficient
on sloccount, and would be error-prone. The purpose of having
roms_helper is that the variables get re-initialised the same
way each time, for each board, automatically.
