Inconsistent static getaddrinfo() behavior on AI_CANONNAME

[fantix]

Testing script:

import socket
print(
 socket.getaddrinfo(
 '127.0.0.1',
 80,
 type=socket.SOCK_STREAM,
 )[0][3], # ai_canonname
 socket.getaddrinfo(
 '127.0.0.1',
 80,
 type=socket.SOCK_STREAM,
 flags=socket.AI_CANONNAME,
 )[0][3], # ai_canonname
)

Testing result:

Platform	flags=AI_CANONNAME	flags=0
Linux glibc	"127.0.0.1"	""
Linux musl	"127.0.0.1"	"127.0.0.1"
macOS	""	""
uvloop	""	""

Expected result: uvloop __static_getaddrinfo_pyaddr() returns consistent result as the platform std C lib returns.

UPDATE: we would expect __static_getaddrinfo_pyaddr() honor the AI_CANONNAME flag.
