perf tools: Drop asm/types.h wrapper

Wrapping the kernel headers is dangerous when it comes to arch
headers. Once we wrap asm/types.h, it will also replace the
glibc asm/types.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.
