fix: Remove stale dump1090 symlink before install check

Browse Source 
If dump1090-mutability was installed by a previous run and later
removed (e.g. by apt removing it as a reverse dep), the symlink at
/usr/local/sbin/dump1090 is left pointing at a non-existent target.
cmd_exists finds the broken symlink and treats dump1090 as installed,
so the real install is skipped and running dump1090 gives
"No such file or directory".

Before the install check, resolve the command path and delete it if
it exists in PATH but is not executable (broken symlink).
