[PATCH] CryptoPkg: add issetugid declaration to fix openssl build on FreeBSD

[rebecca@bluestop.org]

When building OpenSSL, the OpenBSD/FreeBSD/DFBSD code in crypto/uid.c
calls issetugid(). Add the declaration of this function to
CrtLibSupport.h to avoid the need to patch the openssl code on these
platforms.
