x86/Kconfig: Reenable PTDUMP on i386

Browse Source 
commit 4f115596133fa168bac06bb34c6efd8f4d84c22e upstream.

The commit

  f9aad62200 ("mm: rename GENERIC_PTDUMP and PTDUMP_CORE")

has broken PTDUMP and the Kconfig options that use it on ARCH=i386, including
CONFIG_DEBUG_WX.

CONFIG_GENERIC_PTDUMP was renamed into CONFIG_ARCH_HAS_PTDUMP, but it was
mistakenly moved from "config X86" to "config X86_64". That made PTDUMP
unavailable for i386.

Move CONFIG_ARCH_HAS_PTDUMP back to "config X86" to fix it.
