Note: `find_program()` needs a shebang on scripts.

I've re-written this in bash a couple times over the years, and then
I realised python is much more portable and already required by Mesa, so
we might as well make use of it.
I decided to still use the build system's NM instead of re-implementing
symbols extraction, to offload the complexity of keeping it compatible
with many systems (Linux, Unix, BSD, MacOS, etc.), especially when
cross-building.
This new script checks not only that nothing is exported when it
shouldn't be, but also that everything that should be exported is.
Sometimes, some symbols _can_ be exported but don't have to be, in which
case they can be prefixed with `(optional)`.

Meson's vcs_tag() uses the output of `git describe`, eg.
17.3-branchpoint-5-gfbf29c3cd15ae831e249+
Whereas the other build systems used a script that outputs only the sha1
of the HEAD commit, eg.
fbf29c3cd1
Given that this information is used by printing it next to the version
number, there's some redundancy here, and inconsistency between build
systems.
Bring Meson in line by making it use the same script, with the added
advantage of now supporting the MESA_GIT_SHA1_OVERRIDE env var.
