Add nanosecond precision to
File.utime
on Unix (#15335)
`Crystal::System::File.utime` uses `LibC.utimensat` when available, otherwise falls back to `utimes`. The `utimensat` syscall is specified in POSIX.1-2008 and was introduced in the following OS releases: - Linux 2.6.22, glibc 2.6 - macOS 10.14 - FreeBSD 10.3 - OpenBSD 5.0 To keep some backward compatibility, the x86_64-darwin bindings do not declare it. We can however assume the syscalls to be present when compiling for aarch64-darwin. Co-authored-by: Kubo Takehiro <kubo@jiubao.org>
