commit 4fbd4dcc6ee14dc6b739f804cda650725b33c50a
from: Omar Polo <op@omarpolo.com>
date: Tue Nov 29 23:24:21 2022 UTC

define GEMINI_SEARCH_STRING for CGI scripts too

it's redundant since gmid already fills the script argv with the words
extracted from the search string, but 2.0 won't have cgi support and not
all fastcgi <-> cgi wrappers follow RFC3875 § 4.4.  This can help in
preparing scripts for a future when they'll be run under for e.g. slowcgi(8).
