Replace FWRITE with a function
In a few places we use the FWRITE() macro to open a file, replace it's
contents with a given string and close it again. There's no real
reason this needs to be a macro rather than just a function though.
Turn it into a function 'write_file()' and make some ancillary
cleanups while we're there:
- Add a return code so the caller can handle giving a useful error message
- Handle the case of short write()s (unlikely, but possible)
- Add O_TRUNC, to make sure we replace the existing contents entirely
