Squashfs now supports XZ and LZO compression in addition to ZLIB.
As such it no longer makes sense to always include ZLIB support.
In particular embedded systems may only use LZO or XZ compression, and
the ability to exclude ZLIB support will reduce kernel size.

As pointed out by Geert Uytterhoeven, "default n" is the default,
no reason to specify it.

Update compression types supported and add some help text for
the LZO Kconfig option.
Also add missing "default n" line and make some trivial whitespace
cleanups too.
