imap: fix connection when host only has ipv6 address
Some IMAP servers report both IPv4 and IPv6 addresses from their DNS
name:
$ host imap.gmail.com
imap.gmail.com has address 108.177.15.109
imap.gmail.com has address 108.177.15.108
imap.gmail.com has IPv6 address 2a00:1450:400c:c0a::6c
imap.gmail.com has IPv6 address 2a00:1450:400c:c0a::6d
ResolveTCPAddr actually returns the first *IPv4* address by default,
unless the address string is an explicit IPv6 address.
Directly use net.Dial which has a fast fallback mechanism. It first
tries to connect with an IPv6 address (if any) and if that fails, it
will retry with an IPv4 address (if any) before failing completely.
