build: stop checking for __secure_getenv

Currently we check for both __secure_getenv and secure_getenv. The
former was introduced with glibc 2.2.5 as internal(?) API, while the
has been part of glibc 2.17, circa 2012.

Drop the former check. It may have been required over 10 years ago, but
not any more.
