import: use CURLINFO_SCHEME instead of CURLINFO_PROTOCOL

CURLINFO_PROTOCOL has been deprecated in curl 7.85.0 causing compilation
warnings/errors:

../build/src/import/pull-job.c: In function ‘pull_job_curl_on_finished’:
../build/src/import/pull-job.c:142:9: error: ‘CURLINFO_PROTOCOL’ is deprecated: since 7.85.0. Use CURLINFO_SCHEME [-Werror=deprecated-declarations]

      |   ^~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

Since both CURLINFO_SCHEME and CURLINFO_PROTOCOL were introduced in
the same curl version (7.52.0 [0][1]) we don't have to worry about
backwards compatibility.
