perf: use nix::sys::utsname::uname for less syscalls

Browse source 
Instead of reading multiple files to get the `sysname`, `release`, and
`machine` name, use the `nix::sys::utsname::uname` function which sends a
single uname syscall instead. This increases performance and portability.

From my observations, there are ~10 less syscalls.
