Subject: mips: fix vdso32 build, again

The generic vdso support adds the same #if hack in two places,
asm/vdso/vdso.h and config-n32-o32-env.c, but only the second
is actually used. The result lacks the BUILD_VDSO32_64 macro,
and that triggers a build error:

./include/linux/page-flags-layout.h:95:2: error: #error "Not enough bits in page flags"

Move the macro into the other place, and remove the duplicated
bits.

Reported-by: Guenter Roeck <linux@roeck-us.net>
Fixes: ee38d94a0ad8 ("page flags: prioritize kasan bits over last-cpuid")
Fixes: 24640f233b46 ("mips: Add support for generic vDSO")
