scripts/LinuxManBook/prepare_linux_man_book.pl: Add new function BuildSec()

The intention is to move some code from BuildPage() into this function,
reducing the complexity of that inner function.  As a side effect, just
by adding this function, I've already noticed an optimization of 0.3 s.
The reason, I guess, is that it starts processing pages without waiting
for the entire sort to complete, which reduces the latency of the script.
