User and Group Names are not displayed with MUSL Build

This is an odd one. I seem to not be able to see user and group names with `lsd` on a computing cluster I am on, but only when using the MUSL build.

On my local macOS laptop, all is well, but on this SLES 12 cluster, all I see are the numeric UID/GID when I use the MUSL

## Expected behavior
Using GNU ls:
```
$ \ls -l
total 3600
drwxr-xr-x 3 mathomp4 g0620 512 May 19 15:46 lsd-0.17.0-x86_64-unknown-linux-gnu
-rw-r--r-- 1 mathomp4 g0620 930577 May 19 15:46 lsd-0.17.0-x86_64-unknown-linux-gnu.tar.gz
drwxr-xr-x 3 mathomp4 g0620 512 May 19 15:48 lsd-0.17.0-x86_64-unknown-linux-musl
-rw-r--r-- 1 mathomp4 g0620 904892 May 19 15:48 lsd-0.17.0-x86_64-unknown-linux-musl.tar.gz
```
Using "gnu" lsd:
```
$ ./lsd-0.17.0-x86_64-unknown-linux-gnu/lsd -l
drwxr-xr-x mathomp4 g0620 512 B Tue May 19 15:46:55 2020  lsd-0.17.0-x86_64-unknown-linux-gnu

## Actual behavior (using MUSL)
```
$ ./lsd-0.17.0-x86_64-unknown-linux-musl/lsd -l

Obviously for now my "solution" is to use the GNU build, but I thought I'd inform you of this.

Start by reading the linked pull request #431 and the issue's GNU and MUSL command output. Check whether the reported MUSL build behavior is addressed there; done means user and group names are displayed instead of numeric UID/GID on the reported SLES 12 environment.
