cookies: follow-up fix for path checking

The initial fix to only compare full path names were done in commit
04f52e9b4db0 but found out to be incomplete. This takes should make the
change more complete and there's now two additional tests to verify
(test 31 and 62).
curl_easy_perform: avoid busy-looping

When curl_multi_wait() finds no file descriptor to wait for, it returns
instantly and this must be handled gracefully within curl_easy_perform()
or cause a busy-loop. Starting now, repeated fast returns without any
file descriptors is detected and a gradually increasing sleep will be
used (up to a max of 1000 milliseconds) before continuing the loop.
