elf: Add GLIBC_TUNABLES to unsecvars
setuid/setgid process now ignores any glibc tunables, and filters out all environment variables that might changes its behavior. This patch also adds GLIBC_TUNABLES, so any spawned process by setuid/setgid processes should set tunable explicitly. Checked on x86_64-linux-gnu.
