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.
