cannot install xmake on NixOS

Is your feature request related to a problem? Please describe.

install script cannot work on NixOS.

Describe the solution you'd like

xmake works with nix-env to get dependencies or don't require package manager when dependencies existed.

Describe alternatives you've considered

Try to add xmake into nixpkgs.

I don't have a nixos environment to test it now. But you can build source code to install firstly.

I will fail at ./script/get.sh part

you can open a pr to add it.

I found even I install readline by nix-env -i readline, the test_tools() still cannot pass. I guess this is the reason, and I think xmake cannot do much on this.

I have improved get.sh to support nixos on dev branch

[dannypsnl]

New get.sh works. Thanks!
