Make libcurl respect the SSL_CERT_{DIR,FILE} variables by default. The variables
are fetched during initialization to preserve thread-safety (curl_global_init(3)
must be called when no other threads exist).
This fixes network functionality in rust:cargo, and probably removes the need
for other future workarounds.
