There's a merged pull request on the void-packages repository

screen: create /run/screens also at install time
https://github.com/void-linux/void-packages/pull/32201

Description:
After 56db43e, the directory is created at boot time.
This means if one installs screen it won't work until
after the first reboot.

This commit fixes that by creating the directory also
at install time. Note that we still need to create the
directory at boot time, since /run is cleared (tmpfs).
