[pmg-devel] [PATCH pmg-api master v1] config: silence ENOENT when comparing SMTP filter config

[Max R. Carrara]

If `/run/pmg-smtp-filter.cfg` doesn't yet exist when `pmgsync.service`
runs, a "No such file or directory" warning is logged. While this has
been around since a while [0], the warning might look suspicious to
some (as it did to me during testing).

Therefore, handle ENOENT separately without emitting any warnings.
