We want tcache_key not to be a commonly-occurring value in memory, so ensure
a minimum amount of one and zero bits.
And we need it non-zero, otherwise even if tcache_double_free_verify sets
e->key to 0 before calling __libc_free, it gets called again by __libc_free,
thus looping indefinitely.
Fixes: c968fe50628db74b52124d863cd828225a1d305c ("malloc: Use tailcalls in __libc_free")
