jsing and I are investigating removal of all? most? 'getenv from library'
instances.  This one for OPENSSL_ALLOW_PROXY_CERTS gets turned off first,
especially since it had this special comment:
/* A hack to keep people who don't want to modify their software happy */
ok beck jsing
openssl(1) is only built as a single monolithic binary, so just call
load_config() once when we start.

ok miod@
need_cert is now always true, so remove the variable and associated
conditionals.

ok miod@
Remove extra parenthesis.
