Synopsis: sysinst ftp(1) gets Interrupted system call on fetching set via http

State-Changed-Why:
The WITH_SSL implementation handles EINTR, even for non-SSL transfers.
When compiled with !WITH_SSL, the implementation uses stdio, which
may not handle EINTR robustly.
I speculate that the m68k install media is compiled without WITH_SSL.

A potential fix is to always use the ssl.c fetch_*() functions
even without WITH_SSL, and just conditionally remove the ssl-specific
functions in that file. This would deprecate the stdio backend in !WITH_SSL.
