curl: update curl to version 7.43.0

This brings curl to version 7.43.0 and contains fixes for the following
security vulnerabilities:

CVE-2015-3236: lingering HTTP credentials in connection re-use
http://curl.haxx.se/docs/adv_20150617A.html

CVE-2015-3237: SMB send off unrelated memory contents
http://curl.haxx.se/docs/adv_20150617B.html

The 100-check_long_long patch is not needed any more, because the
upstream autoconf script already checks for long long when cyassl is
selected.
