machine-sdk: oldest kernel for x86/x86_64 is 3.2.0 now

With glibc upgrade to 2.26 release (commit d6a0bc57fa07
"glibc: Upgrade to 2.26 final release") it's not possible
to build x86/x86_64 SDK for kernels lower than 3.2.0
(see glibc commit 139ace95756a "Require Linux kernel 3.2
or later on x86 / x86_64.")

Thus drop SDK_OLDEST_KERNEL overrides from machine-specific
conf files, so default version 3.2.0 from conf/bitbake.conf
will be picked up.
