tracing/blktrace: move the tracing file to kernel/trace, fix

Impact: build fix

The BLK_DEV_IO_TRACE entry used to be in block/Kconfig - which
file itself was dependent on CONFIG_BLOCK. But now the entry is
in kernel/trace/Kconfig - which is present even on !CONFIG_BLOCK.

So add a 'depends on BLOCK' to BLK_DEV_IO_TRACE.
