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 by their guards - though the last two aren't actually
exported.
