.github/workflows/build.yml: Remove

Even in theory CI-action-builder cannot work (at first) for any
new upstream change, because downstreams need time to adapt.
Build actually works both via set of git-clones for dependencies and
installing them into a temporary prefix, and also via ladios ebuilds.
Still only the former makes sense in project that does not have
distro specific stuff in-tree, like debian/* or ebuilds.

The jackaudio project's build.yml currently fails on all selected
distros because of new work on control API, the
jackctl_finish_signals() is not adopted in dowstream runners.

Apart from jackctl_finish_signals() adjustment, support for deprecated
long ago in JACK2 non-portable version of signal setup functions
was dropped in commit 6ef4a12163.

For JACK2 internal use, the non-portable variant of the signal setup
functions was dropped in JACK2-1.9.9.5, 11 years ago. See commit
a6a2d8f0e6
