Remove kernel-features.h conditionals on pre-3.2 kernels.

This patch follows up on the increase in minimum kernel version by removing conditionals in non-x86, non-x86_64 kernel-features.h headers that are now constant for all supported kernel versions. * sysdeps/unix/sysv/linux/alpha/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x020621]: Make code unconditional. [__LINUX_KERNEL_VERSION >= 0x030200]: Likewise.
