Default $work_dir is not passed through realpath
_make_customize_airootfs() fails if the working directory is not set with the
-w option since the default
$work_dir is only a directory name which makes it a relative path.
The default values of
$out_dir should be resolved with
realpath as various parts of mkarchiso rely on them being an absolute path.
