Subject: udevd: configure a child process name for worker processes
X-Git-Tag: v253-rc3~29^2~1

udevd: configure a child process name for worker processes

This effectively reverts commit ff86c92e3043f71fc801cf687600a480ee8f6778,
and re-apply 49f3ee7e74c714f55aab395c080b1099fc17f7fd.

The change was dropped due to the process name was not correctly logged,
but the issue was fixed by dd15e4cb57129b915e01495e113696bfe0b70214.
Let's set the child process name again.
