GitHub Actions: update to latest macOS runners (#2293)

Add a simple job with macos-14 on M1.
https://github.blog/changelog/2024-01-30-github-actions-introducing-the-new-m1-macos-runner-available-to-open-source/)
There are some issues with external dependencies (they are installed but
autoconf script doens;t find them) so keep it simple.

On macos-13 it seems that:
* there is no `realpath` program (even if coreutils has been
installed...)
* most of the filesystem is read only (we can't write on /usr/lib).
So I change
```
make install DESTDIR=$(realpath _install)
ls -alhHR _install
```
to
```
DESTDIR=/tmp/ndpi make install
ls -alhHR /tmp/ndpi
```
for all the jobs

Fix a warning on GitHub logs:
```
