ftp: remove #ifdef for define that is always defined

The CURL_FTP_HTTPSTYLE_HEAD logic was added back in 2007 with the
intention to remove that logic one day, but since we never bump the
SONAME it is not likely to happen anytime soon. Remove again for
readability.

Follow-up to 3217809294b

Closes #19463
