Subject: [PATCH 3/3] perf tools: Drop asm/tytes.h wrapper

Wrapping the kernel headers is dangerous when it comes to arch headers.
Once we wrap asm/tytes.h, it will also replace the glibc asm/tytes.h,
not only the kernel one.

This results in build errors on some machines.

Drop this wrapper and do its work from linux/types.h wrapper, also
the glibc asm/types.h can already handle most of the type definition
it was doing (typedef __u64, __u32, etc...).

Todo: Check the others asm/*.h wrappers to prevent from other
conflicts.
