6.8 build appears to be broken on recent compilers

refs #18532

VLC should be compiled with the latest SDK version to benefit from
new features. The currently latest SDK (10.12) already marks
availability for lots of libc functions. Unfortunately, as of now
the autotools configure checks do not support these annotations.
Therefore, lets disable known symbols which are not present on our
minimal macOS version, which is 10.7, currently.

refs #18476

When a new ES is added and selected,
and the p_main_es is deleted, the es selection event
isn't triggered because the es is already selected

Add some missing constraints, set target to 10.7. Fixes some
layout issues when running on 10.7 systems.

As of now, ffmpeg is used for macOS building.

Uses correct kernel version for contribs triplet, instead of
hardcoding one.

Some contribs cannot be compiled by using "xcrun clang" as compiler
variable.

Removal of those variables is done for multiple reasons:
- In general, the caller should set correct variables for compilers,
  this should not be done by the script itself
- In recent macOS versions, default stubs for compilers exist
  (/usr/bin/clang / gcc / cc), so there is not need to use xcrun
  anymore
- Some contribs fail to build with the multi-command notion given by
  xcrun cc, instead they are looking for a tool named "xcrun cc"
  which does not exist

This was yielding false negative when remuxing (as the chain wouldn't
change, while the streams would)

This would cause wrong timing to be used
