Adds a "install-config-files" Makefile target that installs the config
files and dbus policies to DESTDIR=, regardless of whether
--with{,out}-configfiles is specified.

shairport-sync is an executable, shairport-sync(1) ought to be its
documentation, not merely miscellaneous information.
OpenBSD adjusts this in its audio/shairport-sync port/package ever since.
nqptp.c listens on "localhost", but shairport-sync connectes to the wildcard
address 0/0. This apparently works on Linux and FreeBSD, but OpenBSD fails:
```
$ ktrace shairport-sync -v -u
[...]
0.000038288 "ptp-utilities.c:243" *fatal error: error sending timing_peer_list to NQPTP
0.000021868 "shairport.c:1728" emergency exit
$ kdump
[...]
2319 shairport-sync STRU struct sockaddr { AF_INET, 0.0.0.0:9000 }
2319 shairport-sync RET sendto -1 errno 51 Network is unreachable
[...]
```
Resolve and connect to "localhost" just like NQPTP does, resulting in
127.0.0.1 or ::1 as socket addresses.
This is required to run when configured `--with-airplay-2`.
Tested on OpenBSD/amd64 7.4-current with shairport-sync 2.4.3 and nqptp
1.2.5-dev cfa8315 (plus OpenBSD fixes).
I expect Linux and FreeBSD to work as before, but have not tested it.
Update to 4.3.2
**Enhancements**
* A totally new PipeWire backend featuring full synchronisation.
**Bug Fixes**
* Stability improvements for the PulseAudio backend.
* Fix a crash when the Avahi subsystem became disconnected. This is normally a rare occurrence, but Shairport Sync was not dereferencing obsolete data correctly when it happened.
* Set and reset Bonjour flags correctly when it's a Classic Airplay session in AirPlay 2 operation.
* Fix a number of FreeBSD compilation errors and warnings.
* Fix various errors when breaking into an existing session to terminate it. Thanks again to [aaronk6](https://github.com/aaronk6).
* Fix some debug message errors, sigh. Thanks to [Nathan Gray](https://github.com/n8gray).
