lucy adeca21464 Add GNU glibc compatible secure_getenv 
Add mostly glibc and msl compatible secure_getenv. Return NULL if
issetugid() indicates the process is tainted, otherwise getenv(x).  The
rational behind this is the fact that many Linux applications use this
function instead of getenv() as it's widely consider a, "best
practice".
