This fixes a regression after [1] which enabled the CUPS IPP printing
backend. Previously, the only usage of httpConnect2() was a weak symbol
usage in cups_helper.cc, but enabling IPP added a few more codepaths
that don't have the weak check. This CL extracts httpConnect2() usage
to a common location that performs the weak check.
Verified that before this CL, `nm` reports the following:
U httpConnect2
And after:
w httpConnect2
