tests: fix libhostname visibility
I noticed that a patched cmake build would pass tests with a fake local
hostname, but the autotools build skips them:
got unexpected host name back, LD_PRELOAD failed
It turns out that -fvisibility=hidden hides the symbol, and since the
tests are not part of libcurl, it fails too. Just remove the LIBCURL
guard.
Broken since cURL 7.30 (commit
83a42ee20ea7fc25abb61c0b7ef56ebe712d7093,
"curl.h: stricter CURL_EXTERN linkage decorations logic").
