scripts/common: Do not mmap in read_file_2()

Using mmap() in read_file_2() leads to problems because there are
cases where the buffer returned from read_file_2() is modified and
then written back to the same file. This doesn't work when the
original file has been mmapped instead of being read into an allocated
buffer.

Using mmap() was introduced for a usecase where the system is very tight
in memory and bareboximd ran out of memory. Support for this usecase is
removed here, we'll bring it back in the next patch.
