snapcast: fix man page and conf file installation
https://github.com/void-linux/void-packages/pull/24961

Description:
Snapcast 0.21.0 added install targets for the man pages. This causes a file collision of the base and sub packages man pages.
```
# xbps-install snapserver
...
ERROR: snapserver-0.21.0_1: file `/usr/share/man/man1/snapserver.1' already installed by package snapcast-0.21.0_1.
Transaction failed! see above for errors.

# xbps-install snapclient
...
ERROR: snapclient-0.21.0_1: file `/usr/share/man/man1/snapclient.1' already installed by package snapcast-0.21.0_1.
Transaction failed! see above for errors.
```
An install target was also added for the conf file which results in it being installed by the base `snapcast` package in `/usr/etc/snapserver.conf`.
