Subject: [PATCH] shared/dropin: ignore ENAMETOOLONG when checking drop-in
directories (#7525)
This usually happens for device units with long
path in /sys. But users can't even create such drop-ins,
so lets just ignore the error here.
Fixes #6867
Cherry-picked from: dfeec916b57b593ce07d3751aebdb0cce1d05201
Resolves: #1489095
