Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
freesas could not be built reproducibly.

This is because if HOME is not writable (or does not exist), then the
manpages generated by html2man in debian/rules contain a warning
message that reference a randomly-generated path name. For example:

  Matplotlib created a temporary config/cache directory at
  \fI\,/tmp/matplotlib\-89fw1_fi\/\fP because the default path
  (/nonexistent/first\-build/.config/matplotlib) is not a writable
  directory; it is highly recommended to set the MPLCONFIGDIR
  environment variable to a writable directory, in particular to speed
  up the import of Matplotlib and to better support multiprocessing

The "matplotlib\-89fw1_fi" is, of course, nondeterminstic.

Patch attached that sets HOME to a known-writable location.
