Prepare for removing the libc dependency from it.
Make progress on reoving the libc dependency from util_unix, so we can remove the libc dependency for x86_64-unknown-linux-none.

Depending on whether/how #463 is resolved, we may need to unpoison(dest, written) here.

Since the current implementation already doesn't work in MSAN (on Linux), we don't have to block this on MSAN support. |

It isn't clear to me that we actually need to use __X32_SYSCALL_BIT for x86_64-unknown-linux-gnux32 and other x32 targets. It seems like we could just use the 64-bit version of the syscall instead (i.e. same syscall number). But I am not so sure and it's hard for me to test x32.
…-none. Remove the last libc dependency from `linux_android`, as a step towards supporting x86_64-unknown-linux-none. This requires bumping the MSRV to 1.59.
