Change the "imap-send" command to have a hard dependency on libcurl,
before this it had an optional dependency on both libcurl and OpenSSL,
now only the OpenSSL dependency is optional.
This simplifies our dependency matrix my getting rid of yet another
special-case. Given the prevalence of libcurl and portability of
libcurl it seems reasonable to say that "git imap-send" cannot be used
without libcurl, almost everyone building git needs to be able to push
or pull over http(s), so they'll be building with libcurl already.
So let's remove the previous "USE_CURL_FOR_IMAP_SEND" knob. Whether we
build git-imap-send or not is now controlled by the "NO_CURL"
knob. Let's also hide the old --curl and --no-curl options, and die if
"--no-curl" is provided.

I don't have any issue per-se with your proposed change, but perhaps
we can go a step further here. I've had this as part of my local build
for about a year, but never got around to submitting it.
As argued above I think we should just make curl a hard dependency for
"git-imap-send", and that furthermore it's OK to require a newer
version of curl for that utility than we do in general (as the http(s)
transports are more widely required, git-imap-send is more obscure).
