Multiple services cannot have the same links alias refer to different services

[jefferyto]

Describe the bug
When multiple (source) services use the same links alias to refer to different (target) services, the alias ends up referring to the same target service within every source service.

To Reproduce
With this compose.yaml:

services:
  a:
    image: "docker.io/library/alpine"
    entrypoint: [ 'sleep', '600' ]

  b:
    image: "docker.io/library/alpine"
    entrypoint: [ 'sleep', '600' ]

  c:
    image: "docker.io/library/alpine"
    entrypoint: [ 'sleep', '600' ]
    links:
      - "a:foo"

  d:
    image: "docker.io/library/alpine"
    entrypoint: [ 'sleep', '600' ]
    links:
      - "b:foo"

Steps to reproduce the behavior:

1. podman-compose up -d
2. Check the IP address of foo within c and d:

$ podman-compose exec c ping -c 1 foo
PING foo (10.89.0.2): 56 data bytes
64 bytes from 10.89.0.2: seq=0 ttl=42 time=0.135 ms

--- foo ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max = 0.135/0.135/0.135 ms
$ podman-compose exec d ping -c 1 foo
PING foo (10.89.0.2): 56 data bytes
64 bytes from 10.89.0.2: seq=0 ttl=42 time=0.118 ms

--- foo ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max = 0.118/0.118/0.118 ms
$

Expected behavior
foo is an alias to a (10.89.0.2) within c, foo is an alias to b (10.89.0.3) within d.

Actual behavior
foo is an alias to a (10.89.0.2) within both c and d.

What ends up happening is that foo gets 2 IP addresses within all services:

$ podman-compose exec d nslookup foo
Server:         10.89.0.1
Address:        10.89.0.1:53

Name:   foo.dns.podman
Address: 10.89.0.2
Name:   foo.dns.podman
