[PATCH v2 04/22] alpha: select HAVE_DEBUG_KMEMLEAK

Kmemleak needs no architecture support beyond the standard linker script
symbols for the data and bss sections, which Alpha already provides, and
a scan of the kernel stacks, which is done generically.

Assisted-by: Claude:claude-opus-5
Signed-off-by: Matt Turner <mattst88@gmail.com>

Also mark Alpha as "ok" in the kmemleak feature matrix.
