Description:
Inspired by [#2368](https://github.com/void-linux/void-packages/issues/2368#issuecomment-553584051)

<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  
  Void 5.4.32_1 x86_64-musl GenuineIntel uptodate hold rrnFFFFFFFFF
* package:  
  texlive2020-exec [[WIP]](https://github.com/svenper/void-packages/blob/texlive/srcpkgs/texlive2020-exec/template) (which package should be irrelevant but repro timing is hard)

### Expected behavior

The dviout-util subpkg packages just like the others. `.lock` files are reset when repackaging.

### Actual behavior

```

There was a `.lock` file from previous build cancelled midway through packaging. Removing it fixed the problem.

```text
rm /var/cache/xbps-src/binpkgs/texlive/texlive2020-exec-dviout-util-2020.0_1.x86_64-musl.xbps.lock
```

### Steps to reproduce the behavior

Package a package, but cancel it while packaging. Then package again.
```text
./xbps-src -H /var/cache/xbps-src pkg -t -f texlive2020-exec
```
