Miscellaneous problems when trying to build winter

[AlexIII]

First of all, thanks for the awesome work you are doing! 🎉
Submitting here a feedback on the build process.

There are a few problems I've encountered when trying to build from sources with git clone https://github.com/wasmerio/winterjs && cd winterjs && cargo build

I used rust docker image for the build.

1. Problems with libc version.

Full error when running cargo update on the repo (commit cf3c9ae)

error: failed to select a version for the requirement libc = "=0.2.139"
candidate versions found which didn't match: 0.2.151
location searched: Git repository https://github.com/wasix-org/libc.git
required by package rustls-native-certs v0.6.3 (https://github.com/wasix-org/rustls-native-certs.git?branch=main#678174c9)
    ... which satisfies git dependency rustls-native-certs of package hyper-rustls v0.25.0 (https://github.com/wasix-org/hyper-rustls.git?branch=v0.25.0#bb883300)
    ... which satisfies git dependency hyper-rustls of package winterjs v1.1.5 (/home/app/winterjs)

The problem is rustls-native-certs from hyper-rust "doesn't get it" that it needs to use libc v0.2.152. I had to clone both rustls-native-certs and hyper-rust locally, change libc version in rustls-native-certs to v0.2.152, point local hyper-rust to use local rustls-native-certs and finally point winter to use local hyper-rust. That fixed the issue.

2. No human readable error when the system does not have node (npx) installed. This is what I got:

error: failed to run custom build command for winterjs v1.1.5 (/home/app/winterjs)

Caused by:
  process didn't exit successfully: /tmp/cargo-debug-build/debug/build/winterjs-1d5e47ce251dff41/build-script-build (exit status: 101)
  --- stderr

  called Result::unwrap() on an Err value: Os { code: 2, kind: NotFound, message: "No such file or directory" }
  note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

3. Missing npm i before attempting to run npx tsc. I suggest either to add this as the build instruction for people to run npm i manually or add it to the build process. Human readable error also missing for this, it just says

assertion failed: Command::new("npx").arg("tsc").current_dir(dir).output().unwrap().status.success()
