Bug#940488: glslang: add autopkgtest smoke-tests

[Simon McVittie <smcv@collabora.com>]

Source: glslang
Version: 7.10.2984-1
Severity: wishlist
Tags: patch

While backporting glslang to an older Debian derivative, I wanted to check
that the backport was basically functional, so I added simple autopkgtests.
Please consider adding something similar.

I attach the patch I used, but I'm sure a more realistic smoke-test (like
making the tools actually compile a shader, not just show help) would
be straightforward for someone who knows this package better than I do!

Thanks,
    smcv
