These 7 DECOMPRESS_ options (e.g. DECOMPRESS_GZIP) currently have the
tristate type, but can never be set to M. Their only valid values are Y and
N, making them effectively booleans.

Let's make their types more accurate by changing them to 'bool'. Note that
this is only a code cleanup, there is no functional change.

These bistates were found by kconfirm, a static analysis tool for Kconfig.
