decompressors: fix typo "POWERPC"

Commit 5dc49c75a26b ("decompressors: make the default XZ_DEC_* config
match the selected architecture") added

	default y if POWERPC

to lib/xz/Kconfig.  But there is no Kconfig symbol POWERPC.  The most
general Kconfig symbol for the powerpc architecture is PPC.  So let's
use that.
