UAPI: Strip the _UAPI prefix from header guards during header installation
Strip the _UAPI prefix from header guards during header installation so that
any userspace dependencies aren't affected. glibc, for example, checks for
linux/types.h, linux/kernel.h, linux/compiler.h and linux/list.h - though the
last two aren't actually exported.
