Add Solaris Support to Benchee.System

[brianewell]

It would be nice for Benchee to recognize when it's running on Solaris/Illumos platforms instead of just assuming that it's on Linux, ie:

cat: /proc/meminfo: No such file or directory
Something went wrong trying to get system information:

cat: /proc/cpuinfo: No such file or directory
Something went wrong trying to get system information:

Operating System: Linux
CPU Information: N/A
Number of Available Cores: 48
Available memory: N/A
Elixir 1.15.7
Erlang 26.1.2

Would become:

Operating System: Solaris
CPU Information: Intel(r) Xeon(r) CPU E5-2678 v3 @ 2.50GHz
Number of Available Cores: 48
Available memory: 8 GB
Elixir 1.15.7
Erlang 26.1.2
JIT enabled: true

Hi there, thanks for the report! Help is welcome with this - I don't have a solaris system or idea where to get that information in a Solaris information or how to recognize it's Solaris and not Linux.

If anyone could provide that information or even implement the feature I'd be very happy 😁

Otherwise, this will probably wait for a while for me to groom the backlog at some point and be like "ok let's get a VM and dive into this" 😁

This is my first PR for a public elixir library, please let me know if I missed anything: #422

Fixed by #422 !
