After the addition of utmpx, feat_os_unix_musl is now identical to feat_os_unix and is thus not needed any more.

bump libc to 0.2.172
musl provides stubs of utmpx functions, and those stubs are available in the
libc crate version 0.2.172. Thus let's enable the feature so that it can
compile with musl. Note that those stubs always return a success exit value,
and commands such as "users" will report an empty list of users, when calling
those stubs.
This is consistent with the behavior of GNU coreutils which does the same thing.
The coreutils utillities using utmpx are "pinky", "uptime", "users", "who".
This is the expected behavior when using those utilities compiled with those musl utmpx stubs:
```
root@qemuarm64:~# users
root@qemuarm64:~# echo $?
0
root@qemuarm64:~# pinky
Login Name TTY Idle When Where
root@qemuarm64:~# echo $?
0
root@qemuarm64:~# uptime
12:58:47 up 0 min, 0 users, load average: 0.07, 0.02, 0.00
root@qemuarm64:~# echo $?
0
root@qemuarm64:~# who
root@qemuarm64:~# echo $?
0
```

* Disabled `avoid-breaking-exported-api` and sorted items in Clippy.toml
* Renamed `BSD` -> `Bsd`, `SYSV` -> `SysV`, and `CRC` -> `Crc` to match Rust naming rules
* Renamed items in `BackupMode` and `UpdateMode` because they repeated the same word in every item - making it redundant and harder to read
Running this command showed a list of all lints across all crates:
```shell
cargo clippy --all-targets --workspace --message-format=json --quiet | jq -r '.message.code.code | select(. != null and startswith("clippy::"))' | sort | uniq -c | sort -h -r
```
This resulted in a list that I added to the `[workspace.lints.clippy]` in the root Cargo.toml. Afterwards, I commented out a few simpler lints. Subsequentely, I will go through this list, trying to address items in smaller batches.
