Consider replacing sys-info with sysinfo crate?

[unlimitedsola]

Rumors say cargo install bat is failing for some people due to a compilation failure from the sys-info crate. However the fix has not been merged for over half a year and the crate itself hasn't been active for over 2 years now.

There is an alternative crate sysinfo that's more regularly maintained and I believe it should provide similar functionality needed by this project.

Considering the replacement of the crate might change the output format a little, would love to hear your thoughts on this if I should proceed with a PR.

Sounds good, thank you.

Sounds good, thank you.

@sharkdp Made two PRs for this: #18 updates the CI, #17 replaces the crate. Please take a look, thanks!
