Since v4.5, squashfs now ships with `sqfscat` and `sqfstar` utilities. While
they can be invoked with `unsquashfs` arguments, we should just install
them.

Sadly, `install` is stupid and dereferences symlinks, so they have to be
copied/re-created instead.

As squashfs lacks a 'make install' we have to manually install files, so
lets use that, instead of copying.

While here, install into `/usr/bin` not `/sbin`. There is no need to
have root permission to use these tools, only to access any device we
potentially write to.

The builddir hasn't been needed for a while (if it matches the default
pattern) and is useless in this case. Lets remove it.
