squashfs-tools aren't of much use without xz compression support
on OpenWrt, as we build kernel with squashfs supporting only xz.
Enabled support for xz compression by default.

All patches are not needed anymore. squashfs-tools has implemented them in
one way or another.
Converted to download release tarballs. This should work better to get
notified of a newer release.
Also adds support for ZSTD compression:

Otherwise it will pull all compression libraries to install
(on newly configured targets) when maybe 1 or 2 are needed.
