[beatreceiver] replace global path in filebeat generate cmd

[leehinman]

filebeat uses paths.Resolve in the generate command. This is not used in beat receivers.

beats/filebeat/cmd/generate.go

Line 33 in e1d92eb

var defaultHomePath = paths.Resolve(paths.Home, "")

We should investigate to see if we can replace this, but it has no impact on beat receivers.

Relates #44903
