gensquashfs: do pushd/popd when needed instead of chdir
This commit replaces the chdir to the input directory with pushd/popd
when building the fstree and again when packing files.
This simplifies handling of other file paths given on the command line
that have to be accessed and are relative to the original working
directories.
