Subject: [PATCH 3/3] decompressors: make the default XZ_DEC_* config match the selected architecture

This patch changes the defautl XZ_DEC_* config symbol to match the
configured architecture. It is perfectly legitimate to support multiple
XZ BCJ filters for different architectures (e.g.: to mount foreign
squashfs/xz compressed filesystems), it is however more natural not to
select them all by default, but only the one matching the configured
architecture.
