[beatreceiver] replace global paths in auditbeat datastore

[leehinman]

auditbeat used paths.Resolve in two places:

beats/auditbeat/datastore/datastore.go

Line 41 in e1d92eb

path: paths.Resolve(paths.Data, "beat.db"),

and

beats/auditbeat/datastore/datastore.go

Line 55 in e1d92eb

path: paths.Resolve(paths.Data, "beat.db"),

Both of these will need to be replaced with references to:

beats/libbeat/beat/beat.go

Line 92 in 78caa87

Paths *paths.Path // per beat paths definition

when auditbeat is transitioned to a beat receiver.

Relates #44903
