Replace Fiwix filelist with parsing builder-hex0's FS structures

Browse source 
And while we're at it, use a more sustainable way of getting the
address of the next file to be written to.

Since builder-hex0 doesn't distinguish directories from zero-length
files, this has a limitation that it won't copy any zero-length
files or empty directories. Only one such file is important for the
bootstrap process (mes/config.h), which is recreated using an
improve step.
