internal/itoa package unconditionally used in tlssock.go

[darealprism]

tlssock.go incorrectly uses the internal/itoa package, regardless of go version.

net/tlssock.go

Lines 11 to 17 in 1026408

	import (
	"internal/itoa"
	"io"
	"net/netip"
	"strconv"
	"time"
	)

The package is then used here:

net/tlssock.go

Line 31 in 1026408

return JoinHostPort(a.Host, itoa.Itoa(a.Port))

There is already an implementation based on go version in itoa_go126.go and itoa_pre126.go, so this may just be a silly mistake.
