Subject: [PATCH 320/335] gf-event: Handle unix volfile-servers

Problem:
glfsheal program uses unix-socket-based volfile server.
volfile server will be the path to socket in this case.
gf_event expects this to be hostname in all cases. So getaddrinfo
will fail on the unix-socket path, events won't be sent in this case.

Fix:
In case of unix sockets, default to localhost

BUG: 1758923
