ucb: webdav-curl: only set CURLOPT_NOBODY for HEAD

Some testing with Apache httpd+mod_dav reveals that it usually sends a
body with a 401 status, which causes the CURLE_WEIRD_SERVER_REPLY error
code from curl.

So we should either ignore this error in case there's a HTTP status too,
or stop using CURLOPT_NOBODY.

The latter seems to have no downside, except for HEAD requests, where
strangely the server keeps the connection open and curl waits for 5
seconds for no body to arrive, blocking the UI, so continue to use
CURLOPT_NOBODY for HEAD.

The other methods don't seem to block.

It turns out that the SAL_LOG-dependent setting of g_NoBody turned HEAD
into GET anyway if logging is enabled, so explicitly set the method.
