Move from Travis to GitHub Actions

#124

[JonathonReinhart]

A blocker for this effort is that my new code is (properly) detecting this error:

Making staticx executable ($STATICX_FLAGS=):
staticx: /tmp/staticx-pyi-3bnt72x1/_bisect.cpython-35m-x86_64-linux-gnu.so uses unsupported DT_RUNPATH ('/opt/hostedtoolcache/Python/3.5.10/x64/lib').
See https://github.com/JonathonReinhart/staticx/issues/188

In this case it seems that actions/setup-python@v1 and its hostedtoolcache Python builds are partly to blame.

  • Presumably because Deadsnakes PPA has no Python 3.5 package for jammy
    • Even for focal, there is no python3.5-distutils (log)

  • Wait, we're passing -nostdlib and -lnss_dns -lnss_files? How is the linker supposed to find those if we pass -nostdlib? How did this ever work? Is this a GCC / LD version difference?
    • CI:
      • gcc (Ubuntu 11.3.0-1ubuntu1~22.04.1) 11.3.0
      • GNU ld (GNU Binutils for Ubuntu) 2.38

    • Reproduced in ubuntu:22.04 docker container
    • Oops, nope... the problem is missing symlinks: Moved to libnssfix fails to build under Ubuntu 22.04 #245

Thanks @jmsmkn for #224 and the suggestion to use the deadsnakes PPA!
