Delete config via RUST_LIBC_UNSTABLE_LINUX_TIME_BITS64

tgross35 · tgross35 · commit 4a604235379e · 2026-02-14T15:52:24.000-06:00
The internal config `linux_time_bits64` already gets set via the musl or
glibc config, so it isn't useful to be able to set it on its own. Delete
the env option since it isn't used anyway.
