Default profiles do not allow to read `/etc/ld-musl-*.path`
`/etc/ld-musl-x86_64.path` is required to perform dynamic linking. So almost every program will fail to run without it.
An example of this file:
```
/usr/lib/gcc/x86_64-gentoo-linux-musl/13
/lib
/usr/lib
/usr/local/lib
/usr/lib/rust/lib
/usr/lib/llvm/16/lib
```
So this is completely harmless.
Audit log:
```
type=AVC msg=audit(1686087677.497:67): apparmor="DENIED" operation="open" class="file" profile="syslog-ng" name="/etc/ld-musl-x86_64.path" pid=25866 comm="syslog-ng" requested_mask="r" denied_mask="r" fsuid=0 ouid=0
```
This is a one-line addition to `abstractions/base`.
```
@{etc_ro}/ld-musl-*.path r,
```
I will make a merge request.
