[PATCH v2] pstore: turn compression options back to 'bool'

[liaoweixiong]

On commit 58eb5b670747 ("pstore: fix crypto dependencies"),
dependency bug was fixed by selecting the crypto core rather than
turned compression sub-options to 'tristate'.
In addition, these options are used to enable/disable compression. They
are not modules, and mean nothing when set to 'M'.
So, this patch is going to turn them back to 'bool'.
