Colin Watson 5dfa0afa16 getroot: Save/restore CWD more reliably on Unix
Various GRUB utilities fail if the current directory doesn't exist,
because grub_find_device() chdirs to a different directory and then
fails when trying to chdir back.  Gnulib's save-cwd module uses fchdir()
instead when it can, avoiding this category of problem.

Fixes Debian bug #918700.
