porting strace to Bionic libc

[enh]

this okay?

Fix decoding of arm struct stat64 by aarch64 strace.

aarch64's uapi header files have a struct stat but no struct stat64.
To correctly decode a 32-bit process' s struct stat64 we need HAVE_STAT64,
but then the build fails because there is no struct stat64. Luckily,
the aarch64 struct stat is structurally equivalent to the arm struct stat64,
so we can just reuse that.
