[OS-BUILD PATCHv2] redhat: switch the vsyscall config to CONFIG_LEGACY_VSYSCALL_XONLY=y

From: Herton R. Krzesinski <herton(a)redhat.com&gt; redhat: switch the vsyscall config to CONFIG_LEGACY_VSYSCALL_XONLY=y Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1876977 As discussed upstream eg. at https://lore.kernel.org/linux-api/87h7bzjaer.fsf@oldenburg.str.redhat.com/T/ and pointed on the bug's description above, VSYSCALL_XONLY is more secure while still maintaining useful backward compatibility. We also plan to do this change on the RHEL side with a centos-stream-9 change, so the change here covers both Fedora and RHEL/CentOS. v2: move the CONFIG_LEGACY_VSYSCALL* files to the x86 directory, as they are x86 only settings, as reported/suggested by Waiman Long.
