Unix sockets do not work with v1.9.3

[SQUIDwarrior]

I am unable to use the latest grpcurl binary via a Unix socket using the -unix flag. I am using the Linux x86_64 versions from the .tar.gz files.

Here is what I get with 1.8.7:

[root@ip-10-61-110-147 ~]# grpcurl -version
grpcurl v1.8.7
[root@ip-10-61-110-147 ~]# grpcurl -plaintext -unix /var/run/myservice/service.sock list
my.service.api.v1.MyServiceAPI
grpc.health.v1.Health
grpc.reflection.v1.ServerReflection
grpc.reflection.v1alpha.ServerReflection

Here is what I get with 1.9.3:

[root@ip-10-61-110-147 ~]# grpcurl -version
grpcurl v1.9.3
[root@ip-10-61-110-147 ~]# grpcurl -plaintext -unix /var/run/myservice/service.sock list
Failed to dial target host " /var/run/myservice/service.sock": connection error: desc = "transport: error while dialing: dial tcp: address /var/run/myservice/service.sock: missing port in address"

Note I did more testing, and this was introduced in v1.9.2. It works correctly in v1.9.1.

Same issue here on v1.9.3.

This was fixed in #498, but there hasn't been a new release since then.

@dragonsinth are you able to release a new version?
