Subject: units: skip modprobe@.service if the unit appears to be already
 loaded

Possible alternative to #14819.

For me, setting RemainAfterExit=yes would be OK, but if people think that it
might cause issues, then this could be a reasonable alternative that still
let's us skip the invocation of the separate binary.
